I need to verify the current NTP configuration on some Windows systems. Ideally, I'd like to be able to do this via command line instead of navigating through configuration screens.

(I'm working on several different OS versions, and configuration screens tend to not always be in the same place across versions.)

I'm hoping to find a quick, memorable command that I can just punch into a CMD console to get the result. A batch file I can carry around with me will do just as well, though.

Specifically, I need the following:

  • Show whether or not the system is configured to receive time from an NTP server.
  • Show the NTP server(s) the system is receiving time from.
  • Show the time of the last synchronization.
  • Show the current time on the system.

What command(s) would be necessary to achieve these results?

Looking for a solution that's cross-compatible with Windows XP, 7, Server 2003, and Server 2008.

I know to check time you can do "net time \\computername" to get the time of the remote pc. I don't think net time lets you view last sync though... however "net time ?" gives a set option, so it's like 1/2 of what your looking for. – Not Kyle stop stalking me May 16 '12 at 13:26
@Kyle I just figured out that net time /querysntp shows the server. Getting the rest of it might be tricky. – Iszi May 16 '12 at 13:33

In the command line, type

w32tm /query /configuration
w32tm /query /status
Time /T 

w32tm /query /configuration gives you the configuration you have set up.

w32tm /query /status gives you information such as:

  • stratum
  • leap indicator
  • precision
  • last sync
  • NTP server
  • poll interval

time /T outputs the current system time.

Note: w32tm /query was first made available in the Windows Time client versions of Windows Vista, and Windows Server 2008. See Windows Time Service Tools and Settings

No good on XP. "The command /query is unknown." – Iszi May 16 '12 at 16:07
What's the difference between time /t and the time shown on the bottom right of the taskbar? – Pacerier Dec 21 '14 at 14:11

From the command line you can get the info like this:

reg QUERY [\\machine\]HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Parameters
reg QUERY [\\machine\]HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config

Seems like that should be enough at least to get going in that direction, that is, if I understood your question. AFAIK, the 'reg' command works on all these different platforms so long as you have the right services running.

I got: "ERROR: The system was unable to find the specified registry key or value." It turns out W32Time was not started... – msb Mar 13 '15 at 22:21

I tried:

w32tm /query /status

I got:

The command /query is unknown.

Then I tried:

reg QUERY [\\machine\]HKLM\SYSTEM\CurrentControlSet\Services\W32Time

I got:

ERROR: The system was unable to find the specified registry key or value.

Then I tried:

net time /querysntp

I got:

This computer is not currently configured to use a specific SNTP server.

So, basically, the service was not running. Following these instructions, I did:

w32tm /unregister
w32tm /unregister
w32tm /register
net start w32time

Finally, all the above would work. Then I just needed to set my ntp up... I did it with:

w32tm /config /manualpeerlist: /syncfromflags:manual /reliable:yes /update

following instructions from here, but perhaps it could've been as easy as:

net time /setsntp:

as instructed here. ( being my local NTP server)

Take a look at w32tm command-line tool. It can set & query config and report a /stripchart of the time offset with another computer.

The /query option is not available on XP. – Iszi May 16 '12 at 16:08
Try net time /querysntp. – Fran May 16 '12 at 17:10
@Fran That works. I was hoping to get one command that was cross-platform, but it seems I might have to use two different ones - or write a batch file that includes platform detection to determine which command(s) to run. – Iszi May 16 '12 at 17:14
@lszi In my scripts, I test for the existence of C:\users. If I find that folder, I know I'm on a post-XP box. – Fran May 16 '12 at 19:24
@Fran Could you write your own answer that includes both commands? Also, what command would I use to check the last successful sync time for XP? – Iszi Jun 6 '12 at 19:52
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:""
net start w32time
w32tm /config /update
w32tm /resync /rediscover

.BAT Sample File :

I also recommend this program :

This answers your last question:

Open Command Prompt and type exactly:

w32tm /stripchart /computer:NTPServerNameOrIP /dataonly /samples:x(how many returns you want)

Returns time and difference to NTP server time. If it returns time, error: 0x80072746 then that is not your NTP server

Example of command below

Can you please format this answer? – Ramhound Jul 11 at 22:31
The way it self-formats is strange. Have amended – Byron Jul 12 at 22:19
