It is probably "losing" time because it assumes the system clock is set to local time while Linux assumes it is UTC. If either use a network time service to reset the clock, the other will look wrong between reboots. The easiest solution is to use localtime on Linux. Windows can run with the system clock set to UTC but I hear it is rare so it my not be well supported.
