This program uses SNTP (Simple Network Time Protocol) to make a PC's clock accurate by synchronizing it to the time information from an SNTP server.

    or to ask for the time from a server that the user specifies.
  • A secondary server can be set as a backup in case the primary fails.
  • Automatic switching is done between primary and secondary.
  • The user is notified of servers that don't respond.
  • Testing of server response is provided to assure the user that his choice is good.
  • Statistics are kept about the corrections to the PC's clock and the servers used.
  • Logging can be done, and logs can be limited in size or time.
  • A list of the major public servers is provided.
  • The user can customize a list of servers.
