I really wanted to pm the devs on this one but it seems they do not put thier details on the website and pming is locked in this forum so:
There is a bug on some systems where if you add a note to a device in the dude, then press apply, the timestamp is set to jan in 1970.
I found if i pressed ‘ok’ to finalise and close the note, the timestamp is correct.
