Description:
------------
The example in the documentation is IMHO wrong.
time_sleep_until() wants a timestamp as float,
but the example shows getting a value from time().

Here should be used microtime(true) to get a 
float value. The shown example will only work 
accidentally right (without a warning), if 
(time()+0.2) is not allready in the past when
generated. Use microtime() instead here.



Reproduce code:
---------------
---
From manual page: function.time-sleep-until#Beispiele
---
<?php

// Gibt false zurück und generiert eine Warnung
var_dump(time_sleep_until(time()-1));

// funktioniert evtl. nur auf schnellen Rechnern, schläft für bis zu
0.2 Sekunden
var_dump(time_sleep_until(time()+0.2));

?>
