time clock

Does anyone else have trouble with the Sage Time clock not matching the atomic time clock in the cloud?  Is there a time clock in Sage somewhere that can be adjusted?  Mine gets off a minute or two and drives the employees crazy.  They cannot clock in until 6:45 am and the cloud clock says 6:45 but the Sage clock says 6:43 so they end up two minutes late to start work.  Is there a way to fix this?
