time-sync: allow passing an arbitrary time.
During testing it can be useful to set an arbitrary (non-current) time on the device. Extend time-sync to accept an additional (optional) parameter with the time to set. Only changes date / time, no timezone. Change-Id: Ib320777cb245cff19ca00b20540db3a43a4e488f
