|---|---|---|
|
# provides a "random" value to cron based on the last bit of the machine IP address.
|
||
|
# used to avoid starting a certain cron job at the same time on all servers.
|
||
|
# if used with no parameters, it will return a single value between 0-59
|
||
|
# first argument is the occournce within a timeframe, for example if you want it to run 2 times per hour
|
||
|
# the second argument is the timeframe, by default its 60 minutes, but it could also be 24 hours etc
|
||
|
#
|
||
|
# example usage
|
||
|
# ip_to_cron() - returns one value between 0..59
|
||
|
# ip_to_cron(2) - returns an array of two values between 0..59
|
||
|
# ip_to_cron(2,24) - returns an array of two values between 0..23
