Cron scheduling for daemon gem

Does anyone know how to do cron-like scheduling with the daemon gem? basically i need my script to execute every day at 4 a.m. Here's what the default files comes with

while($running) do

  # Replace this with your code   ActiveRecord::Base.logger.info "This daemon is still running at #{Time.now}.\n"

  sleep 10 end

I just need a way to substitute "sleep 10" with "runs every day at 4 a.m." I really looked around but cant seem to find the answer. Btw i tried backgroundrb but I was having problems with it so i'm trying to just do it with daemons. Any help would be greatly appreciated.

If you need to perform some action at particular time then you should test is is a time to action. If time is right, do you thing. If not then sleep a while and then test it once again.

You can have an initial sleeping interval and then you can adjust in correlation how far is the next running time.

What issues you have with backgroundrb (http:// backgroundrb.rubyforge.org/scheduling/)?

yeah I could do that but I was hoping to do something along the lines cron syntax like 0 30 1 * * * *. That would be nice for what I'm trying to do. Or something like :hour => 4. I just dont know the syntax to do that with daemon. I guess if I had to, I could do what you suggest.

I wasn't having problems with scheduling in backgroundrb, was just having issues getting my functions to work. There were many problems but the one I'm having now is I get

Invalid worker with name alerts_worker and key /Library/Ruby/Gems/1.8/gems/packet-0.1.14/lib/packet/packet_connection.rb:52:in `ask_worker'

Besides, backgroundrb probably isn't necessary for the tasks i'm trying to do. I just want to figure out how make scheduling in daemon.
