 == OPTIONS
 
-*-C*, *--cont-clock*[**=**_time_]::
-Activate continuous clock handling for time based UUIDs. *uuidd* could use all possible clock values, beginning with the daemon's start time. The optional argument can be used to set a value for the max_clock_offset. This guarantees, that a clock value of a UUID will always be within the range of the max_clock_offset.
+*-C*, *--cont-clock*[**=**_number_[*hd*]]::
+Activate continuous clock handling for time-based UUIDs. *uuidd* could
+use all possible clock values, beginning with the daemon's start time.
+The optional argument can be used to set a value for 'max_clock_offset'.
+This guarantees that a clock value of a UUID will always be within the
+range of 'max_clock_offset'.

-The option *-C* or *--cont-clock* enables the feature with a default max_clock_offset of 2 hours.
+The option *-C* or *--cont-clock* (without an argument) enables the
+feature with a default 'max_clock_offset' of 2 hours.
 +
-The option *-C<NUM>[hd]* or *--cont-clock=<NUM>[hd]* enables the feature with a max_clock_offset of NUM seconds. In case of an appended h or d, the NUM value is read in hours or days. The minimum value is 60 seconds, the maximum value is 365 days.
+The option **-C**_number_ or **--cont-clock=**_number_ enables the
+feature with a 'max_clock_offset' of _number_ seconds.
+In case of an appended *h* or *d*, _number_ is understood in hours or days.
+The minimum value is 60 seconds, the maximum value is 365 days.
 
 *-d*, *--debug*::
 Run *uuidd* in debugging mode. This prevents *uuidd* from running as a daemon.
