Your domain controller passes down time. It will change any PCs with time that is outside a +/- 5 Minutes from itself. So, all you have to do is set your DC's time. To do so, I always use a program called Symmtime, to set my time to any of a number of internet time servers. To get time otherwise would require you to open up a time port on your firewall, (a security risk)

Symmtime is made by symmetricom, (a time server manufacturer). They may ask for a little bit of information from you, but will not share it or SPAM you. Instead they will let you know of the latest time servers they made.

you can change your DC time to correct time  and put the  below command in logon script for the users :

NET TIME \\ServerName /SET /YES

Ususlly If you change the Time of DC all the client time will also be changed after next login as default sycnchronizion.

However if some of client machine Time is different us can use this command on logon script

NET TIME /domain:mydomainname /SET /Y
