commit 5ad819e37399f563f59e4c0e45a13d4496002f4c
Author: Michael Gratton <mike vee net>
Date: Sun Mar 3 15:51:35 2019 +1100
Clean up protocol date handling substantially
In RFC822.Date, don't use duplicate time_t and GLib.DateTime properties
-- just use the latter, fix formatting of half-hour time zones, fix
where the that class refers to ISO 8601 instead of RFC822 strings since
that is just plain wrong, and finally when parsing an RFC 822 string,
take note of the timezone offset and store that in the DateTime object,
so it is round-tripped correctly.
Stop passing time_t around everywhere else, just use the UNIX time from
the DateTimes we store for protocol objects anyway, so the time zone is
obvious.
Add unit tests.
