That worked, so do you think it will find park position 4 OK?

thanks

If you plate solved the coordinates that would result in an absolute RA/Dec sky position. If you were off by one hour then you could
plate solve and sync (probably all-sky). Rememeber to temporarily turn off "Prevent Errant Recals" in APCC's Advanced settings.

As to why it happened is a mystery. APCC reads the time and time zone from your computer. Maybe your computer didn't update itself
properly if it's not running the latest Windows 10 updates. Or, are you running an old version of APCC or the driver?
