I am working on windows 7. I can sync time of win7 from a ntp linux server manually. How can I do that in command prompt. So I can run it on windows startup. And windows task plan not work for me. The time should be like this:

Linux server -->  windows 7.

Any one knows that? Thank you. I can read msdn.

    @Kayasax w32tm /resync says "The computer did not resync because the required time change was too big." as my CMOS battery is dead and my computer clock resets on every boot at 1/1/2000 12:00 AM. Any help?

    Also if you are on a VM turn off the VMICTimeProvider with the following registry tweak! serverfault.com/a/490619/169771

If you just need to resync windows time, open an elevated command prompt and type:

w32tm /resync

C:\WINDOWS\system32>w32tm /resync 
Sending resync command to local computer 
The command completed successfully.

While the w32tm /resync in theory does the job, it only does so under certain conditions. When "down to the millisecond" matters, however, I found that Windows wouldn't actually make the adjustment; as if "oh, I'm off by 2.5 seconds, close enough bro, nothing to see or do here".

In order to truly force the resync (Windows 7):

  1. Control Panel -> Date and Time
  2. "Change date and time..." (requires Admin privileges)
  3. Add or Subtract a few minutes (I used -5 minutes)
  4. Run "cmd.exe" as administrator
  5. w32tm /resync
  6. Visually check that the seconds in the "Date and Time" control panel are ticking at the same time as your authoritative clock(s). (I used watch -n 0.1 date on a Linux machine on the network that I had SSH'd over into)

--- Rapid Method ---

  1. Run "cmd.exe" as administrator
  2. net start w32time (Time Service must be running)
  3. time 8 (where 8 may be replaced by any 'hour' value, presumably 0-23)
  4. w32tm /resync
  5. Jump to 3, as needed.
