339
            space-separated number of values, each of which is a
 
340
            number and a one-character suffix.  The suffix must be one
 
341
            of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
 
342
            <quote>h</quote>, and <quote>w</quote> for days, seconds,
 
343
            minutes, hours, and weeks, respectively.  The values are
 
344
            added together to give the total time value, so all of
 
345
            <quote><literal>330s</literal></quote>,
 
346
            <quote><literal>110s 110s 110s</literal></quote>, and

            <quote><literal>5m 30s</literal></quote> will give a value
 
348
            of five minutes and thirty seconds.
