i know this sounds kinda strange, but i caught one of my rules (calculating power over time) spewing up strangely wrong values, so i dug in and found out that all items get persisted with timestamps that are 2h, 13min and 47 seconds in the past.
I’m running on openHAB 2.2.0 Build #1009, with a jdbc connection to mariadb 10.2.7 in a dockerized container. openHAB runs on openHABian on Raspberry Pi.
Thank you very much @rlkoshak, that was exactly what happened. Now i just need to teach the qnap container station some manners about the timezone to use
