PMM Virtual Appliance system time wrong

Running the Virtual Appliance (VA), the system time was wrong causing my console to display weirdly timed graphs. I installed NTPD which is working. The PMM server time remains wrong on the console. I assume the server databases (prometheus) is having some problems with the system time. Is this a correct assumption?

If you change the system time does PMM have to be reconfigured? Since it’s the VA I can’t see starting over would make any difference.
