For those that still asking this question.

1. To update, use the command below (2008 and 2012 server compatible)
   
   1	w32tm /config /manualpeerlist:"ntp_server" /syncfromflags:manual /reliable:yes /update

change the ntp_server with your source

2. Restart the time service
   
   1 2	net stop w32time net start w32time

3. Resync the time
   
   1	w32tm /resync

4. Verify your sync status
   
   1	w32tm /query /status

Commands above should be fine if your sources are working correctly and/or your connection is OK (firewall or Microsoft Forefront can be an issue also). The commands below can help with troubleshooting
