Sequoia GPS timestamps


#1

Hello,

I was wondering whether anyone could tell me what the various GPS timestamps reported in the EXIF data refer to?

I get various times that look like below, as you can see, there is a difference between some of them of about 0.25 seconds and I’d like to know which is the actual shutter time to match up with GPS.
