Max execution time is working a bit dependent on the operating system.
On Windows it is using the elapsed time ("wall clock time") on Linux
systems the CPU time. Thus on windows the sleep counts whereas on Linux
no time is spent during sleep(). The same difference happens when other
processes are on CPU and your PHP script was taken off CPU for other
reasons.
For details see MSDN on CreateTimerQueueTimer for Windows and the
setitimer man page with (ITIMER_PROF option) for Linux/Unix for a start.
