I manage a bunch of kiosk style PCs and I have noticed that my test machines have their time drifting a bit.

I'm curious, does anyone know of an freeware time syncing application that can easily be run on a schedule from command line to prevent this drifting?

  • These systems are running Windows XP Embedded.
  • They are not on a domain, so cannot use a DC.
  • They have internet access, but some clients may be limited on outbound comm, it will have to be a case by case basis to config them

I've seen the Atomic Clock Sync from, but I don't see them having any command line utility that would run silently to sync the time.

Thanks for the help

XP Professional has this built-in.

Do w32tm /? for more info.

On Windows 7, when I do this I get: The following error occurred: The service has not been started. – User Feb 12 '13 at 0:06
@User you need to start the Windows Time service beforehand. – vadipp Oct 17 '13 at 11:56

There is one available for download here called Cmdtime 3 (download link is at the bottom of the page, listed under "Tools").
