[pmg-devel] [RFC log-tracker] rfc3339: move timezone offset compatibility code to

[Mira Limbeck <m.limbeck@proxmox.com>]

old time format parsing code

The compatibility code was added to the new rfc3339 code path temporarily so
that the old code path would not be changed before the PMG 8 release.

Now move it to the old time format code to make sure the rfc3339 code path
works as expected. Since we have all the information we need (year, month,
day, hours, minutes, seconds, timezone), there's no need for a workaround in
this code path.

The change needs to be accompanied by one in pmg-api MailTracker.pmg to
keep the time displayed in the GUI the same for the old time format, and
correct for the new rfc3339 format.

After talking to Dominik this might be best sent as an RFC for further
discussions. As such I haven't touched the tests yet.
This change requires changing all tests, including the new rfc3339 ones.

Any code that uses the pmg-log-tracker directly may behave differently
now, since the timestamps it outputs are different than before.
