I ran across this function the other day and would really like to use it, however even though PHPEd recognizes it as a function every time I try to us it in the debugger it comes back as an undeclared. Thus, I went to the ini and still can't figure out which DLL, under windows, needs to be active. Does anyone know how I can solve this problem?

According to http://php.net/manual/en/function.time-sleep-until.php under windows this function available starting from PHP version 5.3.0

May be that is the case?

Thank you and that's the situation. Currently using 5.2 and we aren't upgrading to 5.3 for a while... Thanks for the info.
