比较 Coldfusion 和 PHP 时间戳（以毫秒为单位）
我正在使用自定义函数在 CF8 中创建时间戳。然后它通过查询字符串传递到 PHP 并再次与当前时间戳进行比较（使用 time()）。由于 CF8 没有内置的 DateDiff() 毫秒选项，因此我在返回值（以秒为单位）的末尾附加了 3 个零。
但是，当我将其与 PHP 时间戳进行比较时，差异应该以秒为单位，但我得出了几个小时的差异。
<cfscript>
function GetEpochTime() {
datetime = Now();
return DateDiff("s", "January 1 1970 00:00", datetime) & "000"; //zeroes padded for milliseconds
}
</cfscript>
<cfset foo = getepochtime() /> //Returns time stamp
为了方便讨论，CF 时间戳为 1323344375000。与 PHP 的时间戳值为 1323362710000 相比，差异为 18,555,000 毫秒（超过 300 分钟）。实际过去的时间可能是2秒。
$php_ts = time() * 1000; //PHP timestamp is in seconds, too
$cf_ts = $_GET['coldfusion_timestamp'];
echo $ts_difference = ($php_ts - $cf_ts) / (1000 * 60); //Difference in minutes
我的转换失败在哪里？
I'm creating a timestamp in CF8 using a custom function. It's then being passed via query string to PHP and compared, again, to the current timestamp (using time()). Since CF8 doesn't have a built-in millisecond option for DateDiff(), I appended 3 zeroes to the end of the returned value (which is in seconds).
But, when I compare it against the PHP timestamp, the difference should be in seconds, but I'm coming up with a multi-hour difference.
<cfscript>
function GetEpochTime() {
datetime = Now();
return DateDiff("s", "January 1 1970 00:00", datetime) & "000"; //zeroes padded for milliseconds
}
</cfscript>
<cfset foo = getepochtime() /> //Returns time stamp
For the sake of argument, the CF timestamp reads 1323344375000. When compared against PHP's stamp with a value of 1323362710000, the difference is 18,555,000 milliseconds (over 300 minutes). Real time that has passed is maybe 2 seconds.
$php_ts = time() * 1000; //PHP timestamp is in seconds, too
$cf_ts = $_GET['coldfusion_timestamp'];
echo $ts_difference = ($php_ts - $cf_ts) / (1000 * 60); //Difference in minutes
Where is my conversion failing?

在 GMT 偏移的上下文中，您没有考虑服务器的本地时间。
将 getEpochTime() 修改为：

You're not taking the server's local time into consideration, within the context of the GMT offset.
Modify your getEpochTime() to:
