The GPS navigation message includes the difference between GPS time and UTC. As of July 2015, GPS time is 17 seconds ahead of UTC because of the leap second added to UTC June 30, 2015. Receivers subtract this offset from GPS time to calculate UTC and specific timezone values. New GPS units may not show the correct UTC time until after receiving the UTC offset message.
Coordinated Universal Time (UTC) is the basis for civil time in many places worldwide. Many timekeeping devices use this 24-hour time standard, which is determined using highly precise atomic clocks.
