After an update of OMV pumping up to version 3.0.88, I realised that the date of the OS stays all time to "Wed 2017-09-20". I'm using a Raspbian Jessie as the underlying OS for the Raspberry Pi.
Checking under the Web GUI "System -> Date & Time", I see the same date being set to: Wed 20 Sep 2017 18:30:35 CEST
Even after a reboot, I always see the date above starting with "Wed 2017-09-20".
Only when I untick the "Use NTP Server" check-box, and manually set the date towards today's date in the Web GUI, everything seems to be OK then.
Can anybody enlighten me where I can look further to resolve the issue?
