Is there a command to force the time sync?

This network has only one server, I added a Win client to test and the time is syncing fine. I tried to add an ESXi 5.5 host to sync, but it did not work. Tried to follow the article# 1035833. It failed at the last step, the two commands "service lsassd restart" and "service ntpd restart" both have the same error: "-sh: service: not found".
