Vastool timesync does not appear to be syncing the time with the domain.
For example, set the time back by a few minutes with a command such as the following:
date -s "9 jan 2014 13:15:00" <= Set the time back a few minutes.
Run 'vastool timesync'
The time does not sync, the time on the Unix system is still a few minutes back from the domain.
