title: Dynamic cron jobs?
body: <p>I'm writing a script that needs to be called at a random time during the day, but am not sure how to accomplish this. </p>
  
  <p>I don't want to waste server resources to run a cron job every minute.</p>
  
  <p>I want the script to be called at random, so generating the random times for say a month in advance and then creating cron jobs for each of them isn't what I'm looking for. </p>
  
  <p>Also this script only needs to be executed once a day.</p>
  
  <p>Thanks in advance!</p>
