Auto determine offset #13

Open mlucool opened 6 years ago

mlucool commented 6 years ago

Is there a technical reason gpicsync can't auto-determine the offset between coordinate timestamp to image timestamp? I understand that pictures have a time without a time zone or time since epoch (e.g. they only have something like 08:09:46 on 01/28/2018) so gpicsync cannot convert that to utc, but each coordinate has an implied timezone which can be used to offset automatically.

I have seen packages like timezonefinder, but have not tried them yet.

Any thoughts about adding this?

Thanks for the really useful software!

Thanks! I didn't know that library existed. Not sure when I'll revisit GPicSync but will definitely give this lib a try :)
