I'm not sure if the test case is valid given that according to the spec "The TotalOperationalHours attribute SHALL indicate a best-effort attempt at tracking the length of time".
Overall, those "best-effort" features in Matter are very hard to verify. In this case, the challenge to implement this accurately is that storing the total operational hours too frequently into persistent storage would needlessly wear the flash. Given this and that the attribute has rather low significance for the user, we decided to save the attribute into flash every 10 hours (this is configurable with CONFIG_CHIP_OPERATIONAL_TIME_SAVE_INTERVAL Kconfig option).
I can see that other platforms don't do even that and only save this value when the platform is gracefully shutdown, so if I understand correctly, hard reset will lose the number of operational hours since the last boot.

Hi @Damian-Nordic. Thanks so much for your quick reply! I confirmed again that this is an optional test, and your approach is much more appropriate. So I will close this issue.
