php - set_time_limit is not working as expected? - 


<?php set_time_limit(4); echo  ini_get('max_execution_time'); // give value 4 while ($i<=10)  {     echo "i=$i ";     sleep(1);     $i++; }

output: 4i= i=1 i=2 i=3 i=4 i=5 i=6 i=7 i=8 i=9 i=10

expected behaviour: should end execution after 4 seconds.

please explain ?

you should try this, have script sleeps more maximum execution time.

sleep(ini_get('max_execution_time') + 10);

read : under linux, sleeping time ignored, under windows, counts execution time.

this how can computation time , system calls time.

// script start $rustart = getrusage();  // code ...  // script end function rutime($ru, $rus, $index) {     return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))      -  ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000)); }  $ru = getrusage(); echo "this process used " . rutime($ru, $rustart, "utime") .     " ms computations\n"; echo "it spent " . rutime($ru, $rustart, "stime") .     " ms in system calls\n";

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
