Yep, I can see that. My observation is, before we just jump the gun and
state "everything has to be GMT because it has always been like that",
that first it's not true, I've shown that in my previous mail, and second,
is that the right behavior?
Or should we try to keep the dates for as long as possible in whatever
timezone they were when we read them, and decide on
a conversion at the outskirts of the system, when we have some more
knowledge of what the needs and limits of the target are?
I would like to first have people discuss what the correct behavior is, and
once we have an agreement, go for a fix.
Cheers
Andrea
