6.1 Time Zones and Daylight Saving Time
GPS System Time is a linear timescale that was synchronized with the international UTC timescale (Coor-
dinated Universal Time) when the satellite system became operational in 1980. Since it has entered service,
however, several leap seconds have been introduced to the UTC timescale to adjust UTC time to irregularities in
the Earth’s rotation. While GPS System Time deviates from UTC time by several seconds for this very reason,
satellite messages do incorporate the number of seconds by which these timescales deviate from one another,
allowing GPS receivers to be synchronized internally with the international UTC timescale.
The receiver’s microprocessor can identify any time zone based on UTC time and automatically apply Day-
light Saving Time adjustments over several years if so configured by the user.
