Default value is "0".
+@item segment_clocktime_offset @var{duration}
+Delay the segment splitting times with the specified duration when using
+@option{segment_atclocktime}.
+
+For example with @option{segment_time} set to "900" and
+@option{segment_clocktime_offset} set to "300" this makes it possible to
+create files at 12:05, 12:20, 12:35, etc.
+
+Default value is "0".
+
+@item segment_clocktime_wrap_duration @var{duration}
+Force the segmenter to only start a new segment if a packet reaches the muxer
+within the specified duration after the segmenting clock time. This way you
+can make the segmenter more resilient to backward local time jumps, such as
+leap seconds or transition to standard time from daylight savings time.
+
+Assuming that the delay between the packets of your source is less than 0.5
+second you can detect a leap second by specifying 0.5 as the duration.
+
+Default is the maximum possible duration which means starting a new segment
+regardless of the elapsed time since the last clock time.
+
@item segment_time_delta @var{delta}
Specify the accuracy time when selecting the start time for a
segment, expressed as a duration specification. Default value is "0".
