Hi,

When investigating some login problems on the server-side I noticed lines like this:

2022-12-12 08:03:54 ER1 DEBUG [ER1] PX3 1
2022-12-12 08:03:54 ER1 DEBUG [ER1] PX2 0/0000-00-00
2022-12-12 08:03:54 ER1 DEBUG [ER1] PX3 0
2022-12-12 08:03:54 ER1 DEBUG [ER1] PX3
2022-12-12 08:03:55 ER1 DEBUG [ER1] PX6 0

and

2022-12-12 07:11:39 TGH DEBUG [TGH] PX3 1
2022-12-12 07:11:39 TGH DEBUG [TGH] PX2 -94/2022-09-09
2022-12-12 07:11:39 TGH DEBUG [TGH] PX3 1
2022-12-12 07:11:39 TGH DEBUG [TGH] PX1

2022-12-12 07:11:39 TGH DEBUG [TGH] PX4
2022-12-12 07:11:40 TGH DEBUG [TGH] PX6 4


What caught my attention was that some users have date mentioned there some have just 0000-00-00.

First idea was that it's the last time the user logged in. But for example that ER1 user always had 0000-00-00 there.

What is this date?
What does this DEBUG output mean in general?
