number of base periods to skip. That is, |
The current implementation has hourly(n) –> 2000 + n,
minutely(n) –> 3000 + n, and secondly(n) –> 4000 + n. If n
divides evenly into 3600 for secondly(n)
, the return code will
be the same as hourly(n/3600)
. For secondly(n)
and
minutely(n)
, if n
divides evenly into 60, the return
code will be as if minutely(n/60)
or hourly(n/60)
had
been called, respectively.
For hourly(n)
, n
must evenly divide into 24 and be less
than 24, i.e., n
is one of 1, 2, 3, 4, 6, 8, 12. For
minutely(n)
, n
must be an even divisor of 1440, and less
than 720. For secondly(n)
, n
must divide evenly into
86400, and be no larger than 960.
