I wonder if someone can say how SGP puts the time into the fits header… Where does it get the time from?
I ask as my computer is accurately set to UTC+1 (Madrid time) and displays the time correctly when switched on. When I look at the fits header time of the image, it gives me a time that is wrong.
For example. I have a sub that shows in the Windows explorer as 01:20 and yet in the fits header it is giving a time of 17:19. Looks to me as though the fits header time is 6 hours short of where it should be. If SGP grabs the times from the PC, can anyone explain where I can even start looking for this discrepancy?
