title: How to manipulate time to force Spring schedulers launch?
body: <p>I have a system based on various Spring schedulers. I have used cron and fixedDelay schedulers type. I want to be able to replay all modifications with a minimum effort without wait the real time taken.</p>
  
  <p>Example : I want to replay all modifications with for example 1 second equals 1 minute to speed up my test. For that, I set my current time like -Dtime=2017-01-01T00:00:00Z -Dspeed=1s for 1 minute and my system replay all calls at that speed.</p>
  
  <p>I used in my example -D properties but it can also be programmatically or with an extern tools witch manipulate directly my laptop clock.</p>
  
  <p>Is there a way to do this?</p>
