ISIS Obs time different

[Andrew Smith]

Hi Christian,

I have found a difference in the time of observation in the FITS Image header and the FITS profile header - see attached. It maybe I have some settings incorrect but I can't see where.

Hi Andrew,

did you put an hour shift by mistake in the ISIS general Tab, - Output? In my spectra I always use UT, this is handled correctly by recording spectra in Audela and analyzing in ISIS. It is also possible that Windows mixes up UT and daylight saving time.
