 This matches if the packet arrival time/date is within a given range. All
 options are optional, but are ANDed when specified.

 Only match during the given time, which must be in ISO 8601 "T" notation.
 The possible time range is 1970-01-01T00:00:00 to 2038-01-19T04:17:07.

 Only match during the given daytime. The possible time range is 00:00:00 to
 23:59:59. Leading zeroes are allowed (e.g. "06:03") and correctly interpreted
 as base-10.

 .IP
 Only match on the given days of the month. Possible values are \fB1\fR
 to \fB31\fR. Note that specifying \fB31\fR will of course not match
 on months which do not have a 31st day; the same goes for 28- or 29-day
 February.

 EXAMPLES. To match on weekends, use:
 .IP
--m time --weekdays Sa,Su
+\-m time \-\-weekdays Sa,Su
 .PP
 Or, to match (once) on a national holiday block:
 .IP
--m time --datestart 2007-12-24 --datestop 2007-12-27
+\-m time \-\-datestart 2007\-12\-24 \-\-datestop 2007\-12\-27
 .PP
 Since the stop time is actually inclusive, you would need the following stop
 time to not match the first second of the new day:
 .IP
--m time --datestart 2007-01-01T17:00 --datestop 2007-01-01T23:59:59
+\-m time \-\-datestart 2007\-01\-01T17:00 \-\-datestop 2007\-01\-01T23:59:59
 .PP
 During lunch hour:
 .IP
--m time --timestart 12:30 --timestop 13:30
+\-m time \-\-timestart 12:30 \-\-timestop 13:30

 The fourth Friday in the month:
 .IP
--m time --weekdays Fr --monthdays 22,23,24,25,26,27,28
+\-m time \-\-weekdays Fr \-\-monthdays 22,23,24,25,26,27,28

 (Note that this exploits a certain mathematical property. It is not possible to
 say "fourth Thursday OR fourth Friday" in one rule. It is possible with
