WTH does `last_changed` reset on restart?

I know this is kind of a closed topic, but I would like to revive it for WTH.

After restarting home assistant, the last_changed attribute of every entity gets reset to the restart time.

This is quite annoying when using these states in a dashboard, because the entire dashboard will say everything just changed…

I’ve read there is some sort of technical limitation but i dont care because this is the month of WTH :laughing:

What I’m saying (and much more ;-))

Please search for existing WTH’s before opening new ones. This is already a WTH.
