Currently, when the Oculus Quest system clock is false (maybe it identified the wrong timezone at initial setup; the phone had a wrong clock at setup, you changed your location where there is a different local time, and probably when daylight savings time changes (to be seen)), there is no way other then a factory reset to get the system clock of the quest right again. At factory reset the phone time gets synced with the Quest apparently.
Either add a setting within the Oculus Quest home environment, to change and set the current timezone and sync the time with the network or a online time server; or add an option in the Oculus Companion App to resync the current time with the Quest.
Annoying.
The UK just switched to British Summer Time and now my Quest 2 is an hour slow.
How hard would it be to sync from the phone when it's connected?
No just reboot your oculus quest 2 to go to safe mode just hold the power off button and minus on the volume and scroll up and down with the volume and select reboot with the power button
