Setting clock backwards hangs webserver (PHP+THTTPD)

Hi all, Iam running PHP on THTTPD 2.21b I have a simple php script that sets the system clock (using exec("date -s MMDDhhmmYYYY.ss") and returns a page showing the system time when i use it to set the time forwards, it works fine but if i use it and set the time backwards (even a few seconds), the webserver hangs. also it hangs only for exactly the amount of time needed for the backwards-set time to catch up with the original time. when the clock catches up with the original time, the page is returned. till then it hangs it's almost as if the webserver is waiting for the time to come back to the request-received time before sending the page. i dont know if this is a php problem or a thttpd problem. any pointers, please ?
