Hi guys,

i discovered that timesyncd takes close to 40 seconds to complete during boot. I already switched to local ntp server within my network but still it takes 40 seconds

```

this happen during boot only. If I restart the service later on, it will finish quite fast

Mine started doing that a day or so ago, but stopped after I rebooted a few times today. Doesn’t mean it won’t return, but I also switched to a local NTP server a few minutes ago.

Hi,  
for me a local NTP did not solved it. It’s hanging for 30 seconds during boot now.

Sorry I wasn’t clearer. The hanging stopped before I changed to a local NTP server. I just used your mentioning of your own NTP server to kick my butt into gear and point dietpi to mine. 🙂 Strangely enough, just a few reboots and it stopped hanging. I have no idea why.

strange, indeed. I did quite a lot of reboots the last days for testing purposes and it seems boot times are back to normal. But honestly, I don’t know why. Even more strange, its gone on all my devices like VM, RPi3 and RPi4 at the same time.
