What does UT location stand for? On twitter in the Bio and Location section people use a UT number. I know what the number is, but what does UT stand for? And how do they get it? their cell phone. I found my number using Google Earth or Maps.

UT stands for Univeral Time. Universal Time (UT) is a timescale based on the rotation of the Earth. It is a modern continuation of Greenwich Mean Time (GMT), i.e., the mean solar time on the meridian of Greenwich, and GMT is sometimes used loosely as a synonym for UTC. In fact the expression "Universal Time" is ambiguous, as there are several versions of it, the most commonly used being UTC and UT1 (see below). All of these versions of UT are based on the rotation of the earth compared to distant celestial objects (stars and quasars), but with a scaling factor and other adjustments to make them closer to solar time.
