35                 The number of leap seconds for which data entries are stored
96          by time(2)) at which a leap second occurs or at which the leap second
98          correction, which is the total number of leap seconds to be applied
101          denotes one leap second, either positive or negative, except that if
103          pair denotes the leap second table's expiration time.  Each leap
104          second is at the end of a UTC calendar month.  The first leap second
105          has a nonnegative occurrence time, and is a positive leap second if
106          and only if its correction is positive; the correction for each leap
107          second after the first differs from the previous leap second by
108          either 1 for a positive leap second, or -1 for a negative leap
109          second.  If the leap second table is empty, the leap-second
111          before the first occurrence time, the leap-second correction is zero

177        the last entry denotes the expiration of the leap second table instead
178        of a leap second; timestamps after this expiration are unreliable in
