Discrepancy Detected In GPS Time

jones_supa writes that on Tuesday, 26th January, Aalto University's Metsähovi observatory located in Kirkkonummi, Finland, detected a rare anomaly in time reported by the GPS system (Google translation). The automatic monitoring system of a hydrogen maser atomic clock triggered an alarm which reported a deviation of 13.7 microseconds. While this is tiny, it is a sign of a problem somewhere, and does not exclude the possibility of larger timekeeping problems happening. The specific source of the problem is not known, but candidates are a faulty GPS satellite or an atomic clock placed in one. Particle flare-up from sun is unlikely, as the observatory has currently not detected unusually high activity from sun.

    Reading this, I really feel like I'm living in the future:

    there really should be a way to correct time in a GPS satellite

    1) Press and hold the Set Time button until the indicator lamp lights (5 seconds)
    2) Press + or - until the correct time is reached
    3) Release Set Time button.
