Estimated time (internal clock) is off by 10 minutes

So my Mini+'s internal clock is off from UTC like 10 minutes (shows ETA times in past), and I can't seem to find any way to adjust it (except TZ setting). I read, that it has automatic NTP-scrape for setting the time, but either it's not working or the NTP-server has wring time. Yes, I have it connected to internet via LAN.

 

Any advices, or is this topic, that should be on SW-update requests as "Manual time adjustment"

If I for example start a 7 minute print at 14:00, the printer says "print will end today at 13:57", which I'd say is quite impossible (or timetravel!)

It's not a huge problem, more an inconvinience.

RE: Estimated time (internal clock) is off by 10 minutes

I guess your MINI is connected to ethernet. all the time Your time zone is GMT +2?

Is this 10 minute time shift same for all models you print?

Can you let us know which FW version do you use?

Every detail you can provide is very important.

Yes. It is connected to internet via LAN and the difference is same on all prints. 

Timezone is UTC+0200

FW is newest, 4.3.4

 

Thanks for digging into this! 🙂

RE: Estimated time (internal clock) is off by 10 minutes

This time shift is on your display? What means do you use as a reference time?

Yes, on display and remote connect screen. I compared printers ETA and actual finishing time on multiple prints to 4 different independent NTP-synced devices (Android, iOS, Windows and MacOS), which were all within +-5 sec difference from each other.

RE:

Are you able to replicate it? Would be great to have :

photo of your PC local time

photo of the TZ shift on printer

photo of the print preview screen - with print duration

Hi! 

 

Seems, that now when I try to replicate it it's only 3 minutes off. 'Tho it's still off. 

 

Images attached. Uses my watch, that's synced with NTP and verified in one pic with time.is/

 

Hope this helps!

RE:

Hi thanks, and what was the print duration estimate on the first preview screen?

The display shows the print took 40 min 31s

38min 45sec was the original.

That's about the same amount of estimation excedation in every print due to mesh bed leveling.
