Timers created using Javascripts setTimeout() function will stop working when the computers clock is changed. 


Reproducible: Always

Steps to Reproduce:
1. create a timer in the onLoad function eg.   setTimeout("myfunction", 1000);
2. call the function from itself, eg  function myfunction() { // do something; setTimeout("myfunction",1000); }   so now its running each second
3. change your computers time and it'll stop running
Actual Results:  
The timer is no longer running.

Expected Results:  
Timers should continue to run. It might be acceptable if the currently running timer reset, or completed immediately, but it is clearly screwed up if it stops working altogether

Occasionally the timer has begun running again. Small changes in the time (one minute) sometimes work, larger jumps (minutes, hours, days) will reproduce this bug.

I have to say this seems like a dupe of bug #410706 to me
