Is it possible to modify the Unix Time Clock so that the clock is running ten times faster? Something like a fast-forward by increasing a clock frequency or change the clock tick time?

Background is that i'am waiting here for an application that running on a linux system which has huge timeouts (hourly). I want to bypass these long timeouts with a faked clock. Which side effects can occur here?

  • Do you need the entire system to run fast, or would it be sufficient to restart this one application and have just it run faster? – roaima May 20 '15 at 18:27

You might try writing your own gettimeofday() routine, loading it into a compiled library, and using LD_PRELOAD to have your application get a faked time. This should not affect any other applications.
