Spit out blood, the person upstairs, you try it yourself.
START telnet stdtime.gov.hk 13 -f c:\test.txt
After that, there is a black telnet window hanging there, and you must click the mouse or press a key to make it disappear. The test.txt will have content only after the window disappears, and full automation cannot be achieved!

...I didn't test it in batch processing.
End

It seems that a delay is needed.

You need to add a delay to make it work.

Fellow brothers, still no countermeasures?

```
@echo off
start /b telnet -f time.log stdtime.gov.hk 13
ping -n 2 127.1>nul
taskkill /fi "windowtitle eq Telnet*"
```

I think the original author should be able to complete the final code by themselves. But because a delay was added after TELNET, the time precision obtained has decreased.

Generally use
net time /sntp:time server address
net time /set

Interested to study and have a look
