December 31, 2016 Leap Second

Trimble has made every effort to ensure our receivers will work seamlessly through the addition of one leap second on 31 December 2016. Our current firmware fully supports the introduction of a leap second on 31 December 2016.

In simple terms, the introduction will occur at the UTC cross over between 31 December 2016 and 1 January 2017. GNSS users must determine the time difference from their location to Greenwich Mean Time (GMT) to determine exactly when they should monitor their GNSS receiver.

GLONASS uses UTC in its time system and will introduce a leap second. GLONASS leap second will be introduced at 23:59:60 UTC on 31 December 2016. Any potential issues with tracking of GLONASS will be realized at 00:00:00 UTC on 1 January 2017.
