Go to settings->system->date & time and turn off network provided time and network provided time zone. That sets it to manual mode. If time is correct.then leave it as it is. If time or time zone is wrong then click them and manually change them.
I think OP was saying that if they do that, it can cause intermittent problems (presumably if the phone's date/time doesn't match up exactly with whatever the network thinks it is).
