I found I have to reset the time manually pretty often. As I once mentioned, conversions from Greenwich time to our time zones can be a bit of a nightmare, largely depending on which side of noon or midnight Greenwich is and where you are on the International Date line, which is not a line. Nor, by the way, are the time zone "lines," eg. degrees of longitude, and some areas don't even use Daylight Savings Time (Arizona?).
I long ago decided it was easier to just set it manually for the Center Of My Observable Universe (COMOU, Golden, Colorado), although this time around, it was corrected (105°) with the auto set feature. Yay!
