piCorePlayer v4.1.0 odd Date & Time

There have been some discussions already about time setting in pCP, but I think in my case, there is really something odd going on:
I am running:
piCorePlayer | piCorePlayer v4.1.0 | linux 4.14.81-pcpCore | piCore v9.2pCP | Squeezelite v1.9.0-1121-pCP
(Which I think is the latest version; I installed this version from scratch, so no updates etc)
on a PiZeroW

When I boot, pCP Webpage lists a 1970ies date in the bottom.
(I definetely have Internet access; I also tried to change the time server and also time zone w/o success in correcting the time)

But what is really strange is that when I manually want to change the date via ssh and do i.e. "sudo date 20190126",
the date does not adjust accordingly, but just increments by one year to "Sat Aug 19 01:26:00 CEST 1971"!
If I redo the above sudo command, the date increments again by 1 year. And so on.
So, I can not even manually change the date.

This is more a cosmetic issue, but it bugs me a little and I guess it will cause trouble at some point with plugins, as this is also the date/time LMS is reporting in logs etc.

Is anyone else seeing this with the above pCP build and a PiZero connected via WLAN?
