Know what is UTC? Got another good explanation for UTC? Don't keep it to yourself! Earthquakes, melting ice sheets and natural oscillations in our planet's motion can cause changes of a few fractions of a second in the amount of time it takes the Earth to spin on its axis, according to NASA.

UTC incorporates measurements of the Earth's rotation as well as averaged readings from around atomic clocks around the world, according to the website timeanddate. The U. Army, which divides up the Earth into time zones named after letters of the alphabet, refers to UTC as Zulu time , since it falls in the Z time zone, and Zulu is the code word for that letter in the International Radiotelephony Spelling Alphabet.

As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time.
