I'm new to GrapheneOS, having used DivestOS previously. I picked up a Pixel 4a 5G and am enjoying Graphene so far. One small issue is that although the phone is set to "Set time automatically" the time is a minute or so fast. Any idea what would cause this? Other devices on the same wifi network don't do this, nor do other phones I've tested on the same mobile network (Docomo in Japan, if that's relevant). Of course I could manually set the correct time, but I've never had to before so wondered how to resolve this.
