Description: This value, LSF is the future difference in seconds between GPS time and UTC time as contained in the GPS Almanac UTC data. Leap seconds may be inserted or deleted from the UTC timescale twice during the year: Dec 31 and June 30 at UTC midnight. If this value is the same as gpsAlmLS, then no leap second insertion or deletion will occur at the next possible time. If it is different, then the change will take affect at the time defined by the GPS Almanac parameters, WN_lsf and DN. GPS time will be ahead of UTC time by this amount. For more detailed information, consult the GPS-ICD-200.

What is gpsAlmanacLSF?

Future GPS-to-UTC leap-second difference (LSF) from the GPS Almanac UTC data, which will take effect at the time defined by the almanac's WN_lsf/DN parameters if different from the current LS value.
