Okay I don't know what the hell is going on but in my game time isn't moving. I keep going back to the clock and it says 1.56pm every time. It's pissing me off because I want to catch the Ice Pokemon at shoal cave and it need to be 6.00pm so I can get to them. Do any of you know away to change the time

EDIT
By the way I'm using a cartridge. I should have said that before.
