1020 not showing the correct time of day

[7055]

My Lumia 1020 is not showing the correct time of day (about 2.5 hours fast). When I got it, it did show the correct time of day, but now it doesn't, maybe this could be because I haven't put a sim card in it and activated it yet (just been using the camera). But could anybody tell me how to fix this and why it does this? Thanks

This will probably fix itself when you pit in the SIM card and activate it. If all else fails, manually set your date and time in the settings.
