Is GPS:GPSTimeStamp worth saving?

[wywh]

It seems that in addition to a different timezone, the occasional GPS:GPSTimeStamp or even if its seconds happen to have decimals between 59.996 to 59.999 (!) can cause incorrect sorting in Photos.app:

So: is there any use of the GPS:GPSTimeStamp if the correct time is already in ExifIFD:DateTimeOriginal? AFAIK the time in GPS:GPSTimeStamp is not very accurate so can it be safely deleted? Or is it better to copy the correct time to it (and GPSDateStamp)?

I would say that would be a personal preference thing.  You have to take your workflow into account and what programs you might use in the future.  What if Apple actually fixes the damn thing and things get out of order without it?  What if you switch to an entirely different app and things are out of order without it?

Personally, as long as the EXIF subseconds existed, I would probably correct the GPS value to be equal to the DateTimeOriginal with something like (if you have the OffsetTimeOriginal set)
'-GPSTimeStamp<$DateTimeOriginal$OffsetTimeOriginal'
or manually set the timezone
'-GPSTimeStamp<$DateTimeOriginal -08:00'
