A place located to the east would be ahead in time compared to GMT. Each degree longitude corresponds to 4 min of time difference. Why? Because around the globe, there are 360 deg longitudes which correspond to 1 day of time or 1440 minutes. So each deg = 1440/360 = 4 minutes. So 30 degrees east would have a time of 30*4 = 120 min (2 hours) ahead of 6 a.m. The time at that place is 8 a.m. Hope you got it :)
