The problem is that my clock is stuck. When I fiddle with the "Date and Time Settings" (i.e. I change the format) the time changes to the correct value but is still stuck at that value. Example of stuckyness on image below:
I searched for similar problems but I could not find any solutions. I just hope that this is not the way the clock is meant to be
I tried changing the format of the clock and toggle the network time, but it did not help. Moreover, the "Use network time" could not be turned off. Maybe if I could disable the use of network time the clock would work?
