Folks,
I am running git version 2.43.0 and consider the following config:
$ git config --system --list
core.eol=native
log.date=iso-strict
color.ui=auto
when a commit happens with a zero offset the following is displayed:
osipovmi@deblndw011x:~/var/Projekte/tomcat-native ((ba1454e15...)|BISECTING)
$ git log
commit ba1454e15619a44fe66d86f59c766c0cc25323eb (HEAD)
Author: Mark Thomas <markt@xxxxxxxxxx>
Date: 2024-02-13T08:27:43+00:00

This not right according to the standard in the original language
version, namely in sections:
* 4.3.13 Zeitverschiebung (time shift) (roughly translated from German):
Z denotes that there is no shift from UTC. It also says that you either
have an offset or use "Z"
* 5.3.3 Uhrzeit in UTC (time in UTC) (roughly translated from German):
...the formats from sections ... must be used followed by the UTC marker
"Z" without space.
Throughout the definition neither +0000 for the basic format nor +00:00
for the extended format are used to denote a zero offset from UTC.
The offending code snippet is here:
https://github.com/git/git/blob/945115026aa63df4ab849ab14a04da31623abece/date.c#L344-L352
See also Java's Instant class [1] which is based on ISO 8601 as well is
Java's SimpleDateFormat XXX [2] which will *always* print "Z" in case of
a zero offset.
I'd expect Git to comply with strict since this is why it has been
introduced years ago instead of modifying 'iso'.
Regards,
Michael
