Make sure the daylight savings time settings are correct or it can cause problems syncing appointments. (It can shift the time by an hour.)
P.S. I don't sync my PPC clock with my computer I use GPS Dash which has the option to sync the clock with the GPS signal at each receiver connection, which should definately give good time accuracy.
YEA thats the exact problem im having appointments are an hour behind, daylight savings settings u say? in windows? thanks tryin to find that feature now
