Getting unix timestamp in milliseconds in PHP5 and Actionscript3

Question

In Actionscript, the Unix timestamp in milliseconds is obtainable like this:

public static function getTimeStamp():uint
        {
            var now:Date =          


        

Answer 1

To normalize a timestamp as an integer with milliseconds between Javascript, Actionscript, and PHP

Javascript / Actionscript:

function getTimestamp(){
    var d = new Date();
    return Date.UTC(d.getFullYear(), d.getMonth(), d.getDate(), d.getHours(), d.getMinutes(), d.getSeconds(), d.getMilliseconds()).valueOf();
}

PHP:

function getTimestamp(){
    $seconds = microtime(true); // true = float, false = weirdo "0.2342 123456" format 
    return round( ($seconds * 1000) );
}

See PHP note at "ben at sixg dot com's" comment at: http://www.php.net/manual/en/function.gmmktime.php

EXCERPT: For most intents and purposes you can imagine that mktime() first converts your input parameters to GMT and then calls gmmktime() which produces a GMT timestamp.

So, time() always will return the same thing at the same actual moment, anywhere in the world.
gmmktime() and mktime(), when given specific time parameters, convert those time parameters FROM the appropriate timezone (GMT for gmmktime(), local time for mktime()), before computing the appropriate timestamp.

UPDATE:

On some versions of PHP, the timestamp with milliseconds is too large to display as a string. So use the sprintf function to get the string value:

PHP

function getTimestamp($asString=false){
    $seconds = microtime(true); // false = int, true = float
    $stamp = round($seconds * 1000);
    if($asString == true){
        return sprintf('%.0f', $stamp);
    } else {
        return $stamp;
    }
}
