Thingy91 internal clock goes to quickly with Asset Tracker v2 from 1.9.1 SDK

[Karol Grodzicki (Speeron)]

Hi,

After programming Thingy91 with clean version of Asset Tracker v2 from 1.9.1 SDK I noticed that timestamps of messages sent to cloud are invalid. It looks like on device powered on the clock is synchronized correctly, but then it starts ticking twice too quickly:

There is about 30 minutes difference after 30 minutes of power on. Also I sent two button events with exactly one minute interval and I observed two minutes interval on chart:

  

In Terminal, the last event (13:37:04 in CET time = 12:37:04 UTC) had timestamp 1646656624405, which translates correctly to 12:37:04 UTC, so it's not a matter of displaying (it's sent incorrectly)

I also observed similar issues on modified asset tracker v2 from SDK 1.9.0, but when I used clean asset tracker v2 from 1.8.0 SDK I didn't reproduce the issue. Below we can see that messages sent with one minute interval were indeed one minute apart:

Hi Karol,

We are able to reproduce it and we are looking into it now, thank you for your feedback and we'll come back to you as soon as possible.

Best regards,
