Hi,
I'm navigating my way through quicktime dates and I have a little question about the provenance and differences between some tags.
I've recorded a 2s video on my iPhone at 9:04:17 local time in +2 timezone and I'm getting:
[QuickTime] Create Date : 2020:09:04 07:04:17
[QuickTime] Modify Date : 2020:09:04 07:04:17
[QuickTime] Creation Date : 2020:09:04 09:04:17+02:00
So "Create Date" is in UTC and "Creation Date" is in local time including the time zone.
In your documentation I can find the provenance of Create Date (https://exiftool.org/TagNames/QuickTime.html) as coming from the QuickTime MovieHeader Tags Index4:1 and I can find lots of other dates but nothing called "Creation Date" even though this seems to be a different tag. Is this some kind of composite or a way of getting "Create Date" in local time or does it come from a different source tag?
Thanks for your time. It is very much appreciated.
Best regards,
Frank

CreationDate can be found under Quicktime:Keys (https://exiftool.org/TagNames/QuickTime.html#Keys) and is a separate tag.
Composite tags will always be a part of the Composite group. In your example output, they would have
[Composite] instead of
[Quicktime].
