doublep / datetime Goto Github PK

I am trying to parse a date string which just contains year, month, day immediately concatenated, so 2022-05-06 would be written as 20220506. This is what I try:

(let* ((parser (datetime-parser-to-float 'java "yyyyMMdd" :timezone 'system))
	(parsed (funcall parser "20220506"))))

However, when I execute this, I get

Debugger entered--Lisp error: (datetime-invalid-string "20220506" "yyyyMMdd" "month is out of range")

I get that error even if I add a :non-validating to the parser's options. I think I got the date format string right. Is this a bug?

I'm excited to use this library, as I suspect it may help with many of my Emacs datetime issues. I had a couple questions about how to make some transformations, and I'm hoping you might be willing to help.

1. One common scenario is I have a timestamp like this and I want to get the UTC version:

>>> ts = "2018-06-12T22:10:00+03:00"
>>> pendulum.parse(ts).in_tz('UTC').to_iso8601_string()
'2018-06-12T19:10:00Z'

2. Or I have an org-mode format string and I want the ISO format.

>>> ts = "[2018-06-12 Tue 22:10]"
>>> pendulum.from_format(ts, "[YYYY-MM-DD ddd HH:mm]", tz='America/New_York'
    ).to_iso8601_string()
'2018-06-12T22:10:00-04:00'

I couldn't figure out how to do these in datetime.el. Would you be willing to show how to do this, if that functionality is available? Thanks very much!

What's this problem?

This doesn't necessarily conflict with your library, but in case you ever wanted to add a datetime-format function... :) Just thought you should be aware.

I'm playing around with the nativecomp branch of emacs, and I received a (wrong-number-of-arguments (3 . 4) 2) error on line 1524:

(define-obsolete-function-alias 'datetime-pattern-includes-millisecond-p 'datetime-pattern-includes-second-fractionals-p)

I reviewed the git commit log, and I believe this should be replaced by the following line:

(define-obsolete-function-alias 'datetime-pattern-includes-millisecond-p 'datetime-pattern-includes-second-fractionals-p "0.6.1")
