Try this in EventMachine:

require 'rubygems'
require 'eventmachine'

EventMachine.run {
  EventMachine.add_periodic_timer(60) {
    # The code in this block gets executed every sixty seconds
  }
  EventMachine.add_periodic_timer(3600) {
    # The code in this block gets executed once an hour
  }
}


You can read the timer definitions out of a config file, configure
them dynamically on the fly, or build them with a GUI.
