Is it possible to speed up my Linux Clock?

Question

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? — Chris Davies, 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.
