timetrans

TIMETRANS(1p)						User Contributed Perl Documentation					     TIMETRANS(1p)

NAME

       timetrans - Converts time into time

SYNOPSIS

	 timetrans [units-options] [-count]

DESCRIPTION

       timetrans converts time from one type of unit to another.  If any of the units options are specified, then timetrans will convert those
       time units into the number of seconds to which they add up.  If given the count option, timetrans will convert that number of seconds into
       the appropriate number of weeks, days, hours, minutes, and seconds.  The converted result is printed out.  Units options cannot be
       specified in the same execution as the count option, and vice versa.

       timetrans is intended for use with DNSSEC-Tools, for calculating a zone's expiration time.

OPTIONS

   Units Options
       The converted value of each unit is totaled and a single result printed.

       -seconds seconds
	   Count of seconds to convert to seconds.

       -minutes minutes
	   Count of minutes to convert to seconds.

       -hours hours
	   Count of hours to convert to seconds.

       -days days
	   Count of days to convert to seconds.

       -weeks weeks
	   Count of weeks to convert to seconds.

   Count Option
       The specified seconds count is converted to the appropriate number of weeks, days, hours, minutes, and seconds.

       -count seconds
	   Count of seconds to convert to the appropriate set of units.

   Other Options
       timetrans has the following miscellaneous options.

       -Version
	   Displays the version information for timetrans and the DNSSEC-Tools package.

EXAMPLES

       Example 1:  Converting 5 days into seconds

	   $(42)> timetrans -days 5

       Example 3:  Converting 8 days and 8 hours into seconds

	   $(44)> timetrans -d 8 -hours 8
	   720000

       Example 4:  Converting 1 week, 1 day, and 8 hours into seconds

	   $(46)> timetrans -w 1 -days 1 -h 8
	   720000

       Example 5:  Converting 14 weeks, 4 days, 21 hours, 8 minutes, and 8 seconds into seconds
