[RFD] divecomputer time/date synchronization while downloading dives

[Dirk Hohndel]

Sorry for top post.

How about when you tap the button / check the box that enables time since, we open a pop-up with the current time and ask the user to confirm?
Yeah, I know. Pop-ups are evil. But this does seem like one of those cases where maybe it's worth it? Because I like the time sync idea.

There is one flaw, though, now that I think about it. Usually you download your dives after a day of diving. They may not be the best time to adjust the time zone...

I do like the idea, but I am hesitant about syncing the time with
laptop automatically. That is because it usually takes a few days for
me to update my timezone. Even with the manual time sync, it has
happened to me once that I synced wrong time to my DC. Also with my
tablet, there is no automatic timezone changes so the mobile version
might also be missing the correct time.

I am thinking about a nagging popup in case we have not been diving in
more than a day to remind to set the timezone correctly on computer
before syncing the time (if enabled). Or something less annoying for
the incompetent people who cannot keep their timezones :D Maybe just a
checkbox on the download dialog to enable this feature per DC
connection - maybe even remember the setting until no-fly clears.
