how to sync windows time from a ntp time server in command

Question

Linux server -->  windows 7.

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

Solved my problem thanks. I have a workstation that is domain joined so time settings "Are managed by your organisation" but is is being used away from the domain at the moment. – Nicolas Aug 14 '18 at 15:31

service not start @Kayasax I have run sc start w32time. Windows time service already started. – Nick Dong Apr 04 '14 at 12:19
It runs successfully without error. But time was not change. When I run `time /t`. It make me crazy. @Kayasax – Nick Dong Apr 04 '14 at 12:35
Is there exists a delay? @Kayasax – Nick Dong Apr 04 '14 at 12:38
It will not change other machine in local network and domain, right? – Nick Dong Apr 04 '14 at 12:47
nope, except if you do that on your domain time server – Loïc MICHEL Apr 04 '14 at 12:49
My machine is client. Not domain server. and not time server. – Nick Dong Apr 04 '14 at 12:50
Oh my god. It changes now. Thank you. – Nick Dong Apr 04 '14 at 12:52

@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? – Never Quit Nov 04 '15 at 16:52

@Kayasax Found solution as per http://blog.bruteforcetech.com/archives/911 , do not forget to restart W32Time service `net stop W32Time` then retry `w32tm /resync` – Never Quit Nov 04 '15 at 17:12

Also if you are on a VM turn off the VMICTimeProvider with the following registry tweak! https://serverfault.com/a/490619/169771 – Arvo Bowen Jun 28 '17 at 20:13

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):

Control Panel -> Date and Time
"Change date and time..." (requires Admin privileges)
Add or Subtract a few minutes (I used -5 minutes)
Run "cmd.exe" as administrator
w32tm /resync
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 ---

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