Why did system forget date for a few hours after reboot?
I have cron command that runs a shutdown bash script at 12:10am every day.
10 0 * * * /bin/bash /var/www/scripts/special-reboot.sh
The script is very basic, all it does is shutdown nginx and moves data from MEMORY tables in MySQL to normal tables. Then it performs sudo /sbin/shutdown -r now 'Daily restart.'
It's been running well for about a month or two, however last night something very strange happened and I need to know why.
I have a python logging script which checks that important processes are running every 15 minutes. After the reboot last night, the log looked like this (note the dates and times).

As you can see, it suddenly starts counting from a different date time for about two hours, and then it goes back to normal.
The scariest part is that it wasn't only the python script that was affected. Another C script that tracks electrical pulses is missing data from that period of time.
I don't know what could've caused this. I know, due to my logging script that all of the important programs were running absolutely fine during this time period. I believe this is most likely a problem with the system rather than my programs.
