Summary0000340: Time Zone issues in GPS synchronization
DescriptionOn the Synchronize with GPS Data Files screen, if "Use Local Windows Settings" is selected my local time zone, Atlantic Daylight Time (Halifax, Nova Scotia, Canada), is shown as +5:00 but ADT is actually UTC-3. Because of this problem, "Use Local Windows Settings" is unusable for me.

Also, when I select "Use Time Zone" there is no longer a check box for Daylight Savings Time and the Time Zone listing only has "(UTC-04:00) America/Halifax". I can get around this issue by selecting another time zone with the correct UTC offset like "(UTC-3) America / Bahia" but I don't think that a lot of users will find this intuitive. There should either be a "Use Daylight Savings Time" option in addition to the time zone selection like there was previously or both the Standard and Daylight timezones should be present in the Time Zone listing so the correct one can be selected.

thanks, you're right, this is not correct for all time zones with negative time bias. I already fixed it.

this is only a problem of the user interface. I'm showing only the base time zone in the combo box without DST values. But when synchronizing, each image will be checked for an existing DST which then will be added. You can see it in the synchronization report. Please try it iut. If it doesn't work correctly, please tell me...

NO, please don't. As I said, the DST value will be added automatically. "America / Bahia" perhaps has got other DST policies and you will get wrong results then.

You're right, the user interface seems to be a little bit confusing here because of displaying only the base time zones. I'll try to correct it like this. There are 3 different cases:

1. All images are taken on a date without DST. Then I can leave the entry like it is ("(UTC-04:00) America/Halifax").
2. All images are taken on a date with DST. Then the list will show "(UTC-04:00, DTS+1:00) America/Halifax"
3. The selection of images contain dates with and without DST. The the list will show "(UTC-04:00, some with DTS+1:00) America/Halifax"

Do you think this will help?
