How do I check server sync time?

Procedure

  1. Open a command prompt.
  2. Check time sync: w32tm /query /source.
  3. List NTP server list: w32tm /query /peers.
  4. Update the peer list: w32tm /config /update /manualpeerlist:SPACE_LIMITED_NTP_SERVERS /syncfromflags:manual /reliable:yes.
  5. Force sync: w32tm /resync /rediscover.
  6. Check if the server is now using NTP:
