I am running Ubuntu 14.04 32-bit in a VMWare VM. I suspended the VM for a weak and then resumed it. I noticed that the time/date was incorrect, likely due to the fact that it was still set to the time and date when the VM got suspended. However, after a few hours of use the time was still the same. How often does the date/time get checked when Ubuntu is set to do it automatically?
Note: this question was changed from the original which was about setting the date/time. For some reason I was being locked out of manually changing the date/time through the GUI. The button [Unlock to change these settings] that allows a manual change would not unlock. That issue went away.
