GPS time did originally match UTC in 1980 during its inception but sine that time there have been leap seconds added to UTC to counteract the variations of the earth\u2019s rotation, however the on-board satellite clocks are corrected to compensate for the difference between GPS time and UTC, which is 17seconds, as of 2009.<\/p>\n<p>By utilising a<a href=\"https:\/\/www.atomic-clock.galleon.eu.com\/time-servers\/time-server.html\"> GPS time server<\/a> an entire computer network can be synchronized to within a few milliseconds of UTC ensuring that all computers are safe, secure and able to deal effectively with time sensitive transactions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The GPS (Global Positioning System) systems has revolutionized navigation for pilots, mariners and drivers a like.
