Volkslogger Date Corruption

Last Sunday my Volkslogger logged a flight but it listed the date as 19
Mar 1995 see but the flight was flown on 2 Nov 2014. I uploaded the IGC
to Skylines here (OLC would not accept it):

https://www.skylines.aero/flights/41031/

The "security-seal is OK" message displays on boot and the VL calculates
a check sum before downloading. So I don't think that there is a problem
with the battery.

I have been playing with it and I have generated a number of test logs.
Some are dated 2005-01-01 but now it has gone back to 1995-03-24. I even
managed to generate two logs with the same file name.

The strange thing is I got an e-mail from another club member with a
Volkslogger, he is also experiencing date corruption with his unit. So I
fear this is some form of Y2K bug.

Is anybody else experiencing this problem with their Volkslogger?

Any idea who might be able to fix it, if it requires updated firmware?

Any comments on how valid that log file might be? It does still have a
valid digital signature and the points logged are correct, just the date
header is corrupt.

I know this thing is a dinosaur and getting a log file out of it is like
extracting hens teeth. But this is the first time I have failed to
record a valid log file in over 12 years. I also had the barometric
sensor calibrated at the beginning of this year so I kind of hope it has
not just transformed into an electronic brick. :-(
