I am using Apache 2.2 module on Windows 7 x86/x64. Test script: --------------- microtime(true): <?=$mt=microtime(true)?><br/> time(): <?=$t=time()?><br/><br/> microtime(true) - time(): <?=$mt-$t?><br/><br/> difference should be greater than zero and less than one Expected result: ---------------- PHP 5.4: microtime(true) >= time() microtime(true): 1359313026.5983 time(): 1359313026 microtime(true) - time(): 0.59834909439087 difference should be greater than zero and less than one Actual result: -------------- PHP 5.5: microtime(true) < time() microtime(true): 1359312493.8386 time(): 1359312499 microtime(true) - time(): -5.1614379882812 difference should be greater than zero and less than one ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64085&edit=1
