Re: [misterhouse-users] randomizing time for an event

[David N. <jud...@ad...>]

I think I've come up with a good function for randomizing timed events.  Can
you tell I've been in a coding mood lately?

It takes two arguments.  The first is the same as the time_now function,
'6:45 PM' for example.  The second is an offset in minutes (60), seconds
(:45), or minutes and seconds (2:30).  The function returns true at some
random time between the time specified and the offset.

The offset can only be positive and if you restart between the time
specified and the random offset, it won't fire.
