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 or UTC is the reference point to determine time zone offsets. UTC corresponds to mean solar time on the Prime or Greenwich Meridian (0Â° longitude). Time zone offsets from UTC range from UTC-12:00 to UTC+14:00. Almost all countries in Europe and North America as well as many other countries observe Daylight Saving Time (DST) and put their clocks an hour forward in the spring and an hour back in the autumn.
