There is, kind of.
originally there had to be a compiled in table and you had to specif 
the maximum you would allow (up to 16),
and the sysctl would reduce that maximum. (that may have changed as I 
see it's read-only now for me)
That may change in the future but the hours in the day are still <= 24
