If you go into the hand controller it gives you the option of setting it to utc.  I also   
have Dimension 4 installed on my laptop which keeps it synced to a UTC standard.

Right now I have the hand controller set to standard time and the computer likewise.  Rather than go through the procedure to set the hand controller to DST, can I just go into the keypad, set it to UTC, set the computer to UTS, and not have to do anything else?

The mount won't park itself unless it gets a park command from a 3rd party software. A clock change on your PC does not automatically get sent to the mount by itself, so the mount does not know about any time change.

Last night I was imaging with my QSI683 camera through the AP 130EDF on my Mach1GTO and had an unusual thing happen. I was on my last subframe of the evening, at around 2am and suddenly I noticed that the guiding errors grew tremendously.
I noticed the guide star was out of the field so I grabbed an additional full frame exposure through the guide camera to see what had happened. A 5 sec exposure showed stars streaking in the field of view, like the tracking was incorrect or even off.
After closer inspection I noticed that the mount parked itself at exactly 2:00am when the PC's clock automatically advanced from 2:00am to 3:00am during the EST to DST transition. It wasn't too much of a problem since I was closing down for the night anyway, so I lost the 10 min subframe.
I was wondering why/how the mount automatically parked due to that sudden time shift Any ideas? Anyone else had this happen to them?
