## Commit message ##
- date.c: allow fractional second part of ISO-8601
+ date.c: skip fractional second part of ISO-8601
git-commit(1) says ISO-8601 is one of our supported date format.
- However, we only support RFC-3339 date format.
- We can either:
- - Update documentation from ISO-8601 to RFC-3339
- - Add full support for ISO-8601
+ ISO-8601 allows timestamps to have a fractional number of seconds.
+ We represent time only in terms of whole seconds, so we never bothered
+ parsing fractional seconds. However, it's better for us to parse and
+ throw away the fractional part than to refuse to parse the timestamp
+ at all.
- This series will try to add full support for ISO-8601.
+ And refusing parsing fractional second part may confuse the parse to
+ think fractional and timezone as day and month in this example:

+ ISO 8601::
+ Time and date specified by the ISO 8601 standard, for example
+ `2005-04-07T22:13:13`. The parser accepts a space instead of the
+- `T` character as well.
++ `T` character as well. The fractional part will be ignored.
+ +
+ NOTE: In addition, the date part is accepted in the following formats:
+ `YYYY.MM.DD`, `MM/DD/YYYY` and `DD.MM.YYYY`.
