time's Issues

Arithmetic overflow on Windows

From line lib.rs:250

crates.io version 1.19

Overflow might happen easier on Windows

See tomaka/clock_ticks#4

clock_ticks is based on this library, so I suspect the same issue applies here.

https://github.com/rust-lang/time/blob/a9b589595eaffd9f5b6a4b53bc89a32246204ac2/src/lib.rs#L251

return (ticks as u64 * 1000000000) / (imp::frequency() as u64);

panic Tm::asctime on linux x86_64 systems

Panic when using Tm::asctime at Linux x86_64:

(simplified to reproduce the problem)

extern crate time;
use time::{Timespec, at};

fn main() {
    println!("{}", at(Timespec::new(-0x800000000000000, 0)).asctime());
}

Results in a unreachable panic:

thread '<main>' panicked at 'internal error: entered unreachable code', /home/willem/.cargo/registry/src/github.com-1ecc6299db9ec823/time-0.1.22/src/display.rs:134

At Linux 32-bit system, no panic happens.

Problem is caused by a invalid Tm struct created by 'at':

Tm { tm_sec: 24, tm_min: 21, tm_hour: 17, tm_mday: 32693, tm_mon: 37, tm_year: -1087444786, tm_wday: 0, tm_yday: 32693, tm_isdst: 0, tm_utcoff: 1172, tm_nsec: 0 }

This actually not caused by time crate itself, but is caused by GNU libc implementation of 'localtime_r'.

strptime does not populate all time::Tm fields

This sample code does not what's expected:

extern crate time;
fn main() {

  let t = time::at(time::Timespec::new(236928791,113000000));
  let format = "%Y-%m-%d %T.%f";

  let witness = "1977-07-05 07:33:11.113000000";
  assert_eq!(time::strftime(format, &t).ok().unwrap(), witness);

  assert_eq!(time::strptime(witness.as_ref(), format).unwrap(), t);

}

I wonder if I'm doing something wrong or the library is behaving wrong... ?

PartialOrd for Tm

Is there a reason for PartialOrd (or even Ord?) not being implemented for Tm? It would seem to me like a fairly trivial thing to have and would not require always going between Tm and Timespec.

I would think that something like this should do the trick:

impl PartialOrd for Tm {
    fn partial_cmp(&self, other: &Tm) -> Option<Ordering> {
        self.to_utc().to_timespec().partial_cmp(&other.to_utc().to_timespec())
    }
}

local time format error: rfc822

Issue by zengsai
Friday Aug 29, 2014 at 08:08 GMT

For earlier discussion, see rust-lang/rust#16841

This issue was labelled with: in the Rust repository

Source Code:

extern crate time;

fn main() {
    let utc = time::now_utc();
    let local = time::now();

    println!("utc:   {}", utc.rfc822());
    println!("local: {}", local.rfc822());
}

Console Output:

utc:   Fri, 29 Aug 2014 08:05:12 GMT
local: Fri, 29 Aug 2014 16:05:12 strftime: can't understand this format Z

According to the document of this API, the correct output should be:

utc:   Fri, 29 Aug 2014 08:05:12 GMT
local: Fri, 29 Aug 2014 16:05:12 PST

can't use time on windows

I'm using rust on windows
rustc 0.13.0-nightly (636663172 2014-12-28 16:21:58 +0000)
cargo 0.0.1-pre-nightly (fd5d7a9 2014-12-25 04:28:40 +0000)

I've been using the builtin time crate in my project, but rust complains every time I use anything from it (warning: use of deprecated item: use the http://github.com/rust-lang/time crate instead). So to be a good rust user, I tried adding rust-lang/time to my project with:

[dependencies]
time = "*"

When I go to compile my project, I get the following errors:

(I replaced the full directories with MYHOME and MYPROJECT).

I assume it's trying to call gcc, which I don't have on the path. I've had immense difficulty getting rust to work with cygwin or my own MinGW installations, so the only way I've managed to get things to work on Windows is to let rust use its builtin gcc (as described in https://github.com/rust-lang/rust/wiki/Using-Rust-on-Windows). This seems to be the recommended way of running rust on windows now. Is it possible for time to use that gcc as well?

Build fails on Windows

Now that the time library has been moved to this repository, it has become unusable on Windows. When I run cargo build --verbose in this repository, I get:

unused manifest key: build-dependencies.gcc.git
   Compiling time v0.0.1 (file:///<path removed>)
     Running build.rs
Failed to run custom build command for `time v0.0.1 (file:///<path removed>)`
Could not execute process `build.rs` (status=never executed)

Caused by:
  OS Error 193: %1 is geen geldige Win32-toepassing.

Translation of the OS error: “%1 is not a valid Win32 application”.

When I add time as dependency of an other project, and run cargo build --verbose, I get:

   Compiling time v0.0.1 (https://github.com/rust-lang/time.git#d6219df8)
     Running build.rs

Caused by:
  file not found (OS Error 2: Het systeem kan het opgegeven bestand niet vinden.)

Translation of the OS error: “File not found.”

When the time library was included in the standard library, a binary version was included with the installer, so users did not have to have all the tools and dependencies available to build this. Also, getting a working version of GCC on Windows is not trivial at all in my experience.

timezone support for strftime

When I use time::strftime("%Y-%m-%d %H:%M:%S %Z", &time::now()).unwrap(), I get timestamp without timezone. Here is output I get. 2014-12-18 12:32:31

How do I get timezone printed?

Here is equivalent python code

import datetime
import pytz
d = datetime.datetime.now(pytz.timezone("America/New_York"))
d.strftime("%Y-%m-%d %H:%M:%S %Z")

'2014-12-18 12:41:19 EST'

Parsing Fractional Seconds

As far as I can tell, strptime only has one option in order to parse fractional seconds: %f. Unfortunately, this is really inconvenient since it expects nine digits and thus a time format such as 2014-12-27 10:11:12.3215 currently cannot be parsed.

properly parse timezones

I'm not sure about the policy here but right now the timezones are not parsed correctly which makes working with timestamps from different timezones impossible unless done by hand.

I'm referring to %z here and not %Z .

Any thoughts on this?

In looking for what The system cannot find the file specified. might mean, I found that the time_helpers.o file was missing. The directory exists, but the .o file is not there.

Because it's mentioned here, you should know there are multiple gcc.exes in my system, but none of them are in my PATH. The gcc it should be using then is the one at C:\Program Files (x86)\Rust\bin\rustlib\x86_64-pc-windows-gnu\bin\gcc.exe. Here's its version info:

Compatibility with Duration

A couple of questions/issues:

I see that Timespec + Duration is implemented, but is there a reason for Timespec - Duration to not be implemented?
Is it intended that Tm offers no compatibility with adding and subtracting Durations? Since Timespec offers (some) compatibility, It would seem fairly easy convert to a Timespec, perform the addition, and then convert back to Tm afterwards (although I guess there could be more efficient ways of achieving this).

A trivial reproducer is here: https://github.com/jgallagher/building_time. I'm not sure this is an issue with time - maybe a Cargo bug?

time_helpers.c redefines the timegc structure which is what is causing the error. There is a comment saying that it isn't defined on Android - which it might not be - but it appears to be defined in the header files used by the android cross compiler in ubuntu. If I comment out that structure (starting around line 42) everything seems to work fine.

strptime and time zones

strptime is not handling time zones correctly. For example, if you use the format string "%FT%T%z" with ISO 8601 strings like
1999-05-31T13:20:00-04:00
and
1999-05-31T13:20:00-05:00
you get identical results back.

The code on line 510 seems seems to match the time zone offset but it only does something when the offset if zero.

Question about tm_yday

I have a question. I tested following code using rust-lang/time ver 0.1.26.

let t = Timespec { sec: 1451606399, nsec: 0 }; // timestamp of 2015-12-31 23:59:59
println!("{:?}", at_utc(t));

And I got output

Tm { tm_sec: 59, tm_min: 59, tm_hour: 23, tm_mday: 31, tm_mon: 11, tm_year: 115, tm_wday: 4, tm_yday: 364, tm_isdst: 0, tm_utcoff: 0, tm_nsec: 0 }

I expected tm_yday to be 365 because tm_yday is up to 365 in document.

Is tm_yday up to 364 in fact?

Serialization support

Hi,

Is there any plan to have full rustc-serialize support for the whole lib? Using time::Timespec forced me to use custom Json mapping instead of simply annotate my struct with RustcEncoable.

Thanks

libtime::Tm::to_utc() is slow even if already utc

Issue by seanmonstar
Friday Nov 07, 2014 at 01:29 GMT

For earlier discussion, see rust-lang/rust#18725

This issue was labelled with: in the Rust repository

Tm.to_utc() calls out to the runtime fn rust_timegm twice, once to convert to a Timespec, and a second time to convert the timespec to a new Tm with offset of 0. If a Tm is already UTC, this should skip both those calls.

libtime locale values

Issue by saosebastiao
Thursday Sep 18, 2014 at 17:32 GMT

For earlier discussion, see rust-lang/rust#17374

This issue was labelled with: in the Rust repository

libtime currently uses what appears to be en_US.UTF8 locale definitions hardcoded into the strftime/strptime functions.

https://github.com/rust-lang/rust/blob/master/src/libtime/lib.rs#L512-L548

These values should be derived from system-level locale definitions, such that they can be used in different locales correctly. However, I'm not sure how this would work for different operating systems/architectures. Is there a cross-platform standard practice that should guide the design of these parsing/formatting functions?

Remove C dependencies

I recently had to compile a Rust project with time as a dependency and I went through a lot of trouble having to get mingw64 on my 64 bit machine and messing around with paths to make sure that's the version that's used and not the 32 bit version. (I have 64 bit Rust and 32 bit C mingw)

Is it possible to remove the C dependencies so this project uses only Rust? That would make compiling projects with time as a dependency much easier on Windows.

Error in Build script-can't compile any package depending on time

Here's the message I'm getting:

Only `-l` and `-L` flags are allowed in build script of `time v0.1.4 (https://github.com/rust-
lang/time#67fb5a7f)`: `-L /Volumes/Mac Data/gabe/Workspaces/piston-
tutorials/r_tetris/target/build/time-040b8fe6da930644/out -l time_helpers:static`

This happens in literally every example I've tried to compile that depends on (directly or indirectly) the Rust time package. In this case, I was trying to compile the r_tetris project, which is a simple example Tetris game showing off some of the features of Piston.

This error comes up during the cargo build, and as far as I can tell there's no way to stop the error. Is this a glitch with this package or a problem with my Cargo config?

std::num::SignedInt doesn't exist

Hi.

I was installing time while playing with iron for web development and i found this error:

home/vampolo/.cargo/git/checkouts/time-d59bff975f117a1a/master/src/lib.rs:23:5: 23:24 error: unresolved import `std::num::SignedInt`. There is no `SignedInt` in `std::num`
/home/vampolo/.cargo/git/checkouts/time-d59bff975f117a1a/master/src/lib.rs:23 use std::num::SignedInt;
                                                                                  ^~~~~~~~~~~~~~~~~~~

Looks like that in stable Rust that has been renamed to std::num::Int.

strptime() not handling optionality of leading zeroes

For many format specifiers, leading zeroes are supposed to be optional: http://pubs.opengroup.org/onlinepubs/7908799/xsh/strptime.html

I have only tested %m.

[package]
name = "test"
version = "0.0.0"
authors = [ "[email protected]" ]

[[bin]]
name = "test"
path = "main.rs"

[dependencies]
time = "*"

extern crate time;

use time::strptime;

fn main() {
    // %m is the month number [1,12]; leading zeros are permitted but not required.
    let format = "%d/%m/%Y".into_string();
    let dates = [ "24/05/2016", "24/5/2016" ];

    for date in dates.iter() {
        match strptime(*date, format.as_slice() ) {
            Ok(d) => println!("{} is valid {}, result shows as {}", date, format, d),
            Err(e) => println!("{} is invalid {} -- {}", date, format, e),
        }
    }
}

24/05/2016 is valid %d/%m/%Y, result shows as Tm { tm_sec: 0, tm_min: 0, tm_hour: 0, tm_mday: 24, tm_mon: 4, tm_year: 116, tm_wday: 0, tm_yday: 0, tm_isdst: 0, tm_utcoff: 0, tm_nsec: 0 }
24/5/2016 is invalid %d/%m/%Y -- Invalid month.

strptime add support to convert epoch time string

Hi,

i am trying to convert an epoch time in seconds to a time::Tm.
It seems that "%s" format is not recognized, I get an InvalidFormatSpecifier('s') in my example below.

extern crate time;
use time::strptime;

fn main() {
    let format = "%s";
    let date = "1236905626";

        match strptime(date, format ) {
            Ok(d) => println!("{} is valid {}, result shows as {:?}", date,  format, d),
            Err(e) => println!("{:?}", e),
        }
}

This is the version I used:

MSYS2 64-bit's gcc does not define `WIN32` by default

I'm getting an error for missing symbols in time_helpers.c:

note: D:\Git\img_dup\target\deps\libtime-040b8fe6da930644.rlib(r-time_helpers-time_helpers.o):time_helpers.c:(.text$rust_time_gmtime+0x27): undefined reference to `gmtime_r'
D:\Git\img_dup\target\deps\libtime-040b8fe6da930644.rlib(r-time_helpers-time_helpers.o):time_helpers.c:(.text$rust_time_localtime+0x27): undefined reference to `localtime_r'
ld: D:\Git\img_dup\target\deps\libtime-040b8fe6da930644.rlib(r-time_helpers-time_helpers.o): bad reloc address 0x27 in section `.text$rust_time_localtime'

This is a fresh MSYS2 install, plus gcc grabbed through the included pacman.

It looks like the C preprocessor isn't predefining __WIN32__ unless -mwin32 is passed:

$ gcc -m64 -dM -E -x c /dev/null | grep "WIN"
#define __WINT_MAX__ 4294967295U
#define __WINT_MIN__ 0U
#define __SIZEOF_WINT_T__ 4
#define __CYGWIN__ 1
#define __WINT_TYPE__ unsigned int

$ gcc -mwin32 -dM -E -x c /dev/null | grep "WIN"
#define _WIN32 1
#define __WINT_MAX__ 4294967295U
#define __WINT_MIN__ 0U
#define __WIN32 1
#define __WIN32__ 1
#define __SIZEOF_WINT_T__ 4
#define __CYGWIN__ 1
#define WIN32 1
#define __WINT_TYPE__ unsigned int
#define WINNT 1

Not sure if this belongs here or gcc-rs. Patching time to add the -mwin32 flag for target_os = "windows" did the trick, then I needed to get tchar.h from pacman -S mingw-w64-x86_64-headers and copy it into /usr/include.

formatting with alignment fails

hey, I'm learning rust and re-writing a very basic cal in order to learn. ran into a strange formatting bug:

extern crate time;

fn main() {
    // not aligned (bug in TmFmt Display impl?)
    println!("{:>11}", time::now_utc().strftime("%B").ok().unwrap());
    // aligned properly when forced into a string
    println!("{:>11}", time::now_utc().strftime("%B").ok().unwrap().to_string());
}

know what's going on here? i don't think i should have to call .to_string() in order to get the alignment...?

SteadyTime implementation/documentation is wrong.

Documentation claims

/// SteadyTimes are generated by a "steady" clock, that is, a clock which
/// never experiences discontinuous jumps and for which time always flows at
/// the same rate.

but it is implemented in terms of CLOCK_MONOTONIC on linux, which does not flow at the same rate in case NTP works or adjtime is called.

Either should use CLOCK_MONOTONIC_RAW or not claim time always flows at the same rate.

Re-publish to crates.io.
