title: Prevent TeamCity builds running out-of-hours?
body: <p>I have some builds that I do NOT want to run out of business hours (they are integration tests that depend on a third party system that is unavailable overnight). Can TeamCity be configured to only run certain builds at certain times, or rather NOT run a build between 10pm and 8.30am?</p>
  
  <p>It looks like I might be able to write a plugin to do this using the StartBuildPrecondition hook, but I was wondering if this existed already?</p>
  
  <p>Thanks
  Matt</p>
