PHP strtotime and JavaScript Date.parse return different timestamps
提问by Puzzled Boy
I am getting same date time seconds value in JavaScript which is given by strtotime()in PHP. But i need same value in JavaScript.
我在 JavaScript 中获得了相同的日期时间秒值，该值由strtotime()PHP给出。但我需要在 JavaScript 中使用相同的值。

PHP代码
echo strtotime("2011-01-26 13:51:50");
// 1296046310
JavaScript Code
JavaScript 代码
var d = Date.parse("2011-01-26 13:51:50");
console.log(d);
// 1296030110000

You need to use the same time-zone for a sane comparison:
您需要使用相同的时区进行合理的比较：
echo strtotime("2011-01-26 13:51:50 GMT");
// 1296049910
var d = Date.parse("2011-01-26 13:51:50 GMT") / 1000;
console.log(d);
// 1296049910

According to the standard, only RFC 2822 formatted dates are well supported:
根据标准，只有 RFC 2822 格式的日期得到很好的支持：
Date.parse("Wed, 26 Jan 2011 13:51:50 +0000") / 1000
To generate such a date, you can use gmdate('r')in PHP:
要生成这样的日期，您可以gmdate('r')在 PHP 中使用：
echo gmdate('r', 1296049910);

JavaScript uses milliseconds as a timestamp, whereas PHP uses seconds. As a result, you get very different dates, as it is off by a factor 1000.
JavaScript 使用毫秒作为时间戳，而 PHP 使用秒。因此，您会得到非常不同的日期，因为它相差 1000 倍。

echo date('Y-m-d', TIMESTAMP / 1000);
echo date('Y-m-d', TIMESTAMP / 1000);

echo $the_date = strtotime("2011-01-26 13:51:50");回答by Salman A
strtotime()and Date.parse()yield UNIX timestamps with a resolution of seconds and milliseconds respectively. However, if timezone information is missing from the input string, local time is assumed. So the input string 2011-01-26T13:51:50may produce different output on different machines even if PHP (or JavaScript) is used to generate the timestamps on both machines.
strtotime()并Date.parse()产生分辨率分别为秒和毫秒的 UNIX 时间戳。但是，如果输入字符串中缺少时区信息，则假定为本地时间。因此，2011-01-26T13:51:50即使使用 PHP（或 JavaScript）在两台机器上生成时间戳，输入字符串也可能在不同机器上产生不同的输出。
The solution is to explicitly specify the timezone in the strings. This should produce the same result on any machine:
解决方案是在字符串中明确指定时区。这应该在任何机器上产生相同的结果：
Date.parse("Jan 26, 2011 13:51:50 GMT+0500") / 1000; // 1296031910
strtotime("Jan 26, 2011 13:51:50 GMT+0500"); // 1296031910
