date and time of day in the transmitted sentences. Prior to
the initial position fix, the date and time of day are provided
by the on-board clock. After the initial position fix, the date
and time of day are calculated using GPS satellite

satellites to add or delete UTC leap seconds and correct the
transmitted date and time of day. The transmitted date and
time of day for leap second correction follow the guidelines
