The error is correct. There is not sufficient information to parse a date, as only the last two digits of the year are known. As a result, it is ambiguous.
Side note: parsing also does not work if the weekday and month are in all caps
You need to explicitly permit case-insensitive matching. This is done with a case_sensitive:false
in both weekday and month as indicated in the format description documentation.
from time.
Caused by these TryFrom impl for Date not considering year_last_two option.
In these lines:
https://github.com/time-rs/time/blob/bb397df38e5316d767ca3f3bd148e506b7af5587/time/src/parsing/parsed.rs#L758C1-L780C47
from time.
The source of confusion for me around the [year]
component was due to the docs:
Note that when parsing, if only the last two digits of the year are present, the value returned may not be what was expected — if the return is successful at all (it's not guaranteed).
On first reading I interpreted this to mean that I could get back 1923 when I want 2023.
On second reading this sentence is ambiguous about whether parsing with repr:last_two
is supported or not. Maybe this could be worded more clearly.
from time.
That description is a long-winded way of saying there are no guarantees. Either Ok
or Err
can be returned, and in the former it could use any century.
