Step values can be used in conjunction with ranges. Fol
lowing a range with ``/<number>'' specifies skips of the
number's value through the range. For example, ``0-23/2''
can be used in the hours field to specify command execu
tion every other hour (the alternative in the V7 standard
is ``0,2,4,6,8,10,12,14,16,18,20,22''). Steps are also
permitted after an asterisk, so if you want to say ``every
two hours'', just use ``*/2''.
Perhaps overkill for the half hour but how bout for every 15 minutes
Now you would want to use */15 I think.
