UTC (Universal time coordinated) is atomic time based on electronic transitions in atoms. GMT is astronomical time based on rotation speed of Earth. The difference is adjusted twice each year in July and December by adding or removing a second or two from clocks. The correction cannot be known until the earth has decided just how fast it wants to spin.
Until operating systems acquire a capability for accounting for leap seconds the two times can be considered the same and the question is only that of English usage. Perhaps it's the other way in some other locale?
If you set the computer clock using the internet once a day you're surely using atomic time corrected for any previously known leap seconds. That would be GMT.
And (OT). . . If the ocean waters are rising due to heated water from polar regions the moment of inertia of Earth is increasing. Why don't we see a slowing down of the planet, as an ice skater, when we are regularly measuring the rate to a microsecond or so?
