date_timestamp_set

(PHP 5 >= 5.3.0, PHP 7)

以 Unix 时间戳的方式设置 DateTime 对象

说明

以 Unix 时间戳的方式设置 DateTime 对象的日期和时间。

参数

仅过程化风格：由date_create()返回的DateTime类型的对象。此函数会修改这个对象。

表示日期时间的 Unix 时间戳。

返回值

返回被修改的 DateTime 对象，或者在失败时返回FALSE.

范例

以上例程的输出类似于：

1272508903 = 2010-04-28 22:41:43
1171502725 = 2007-02-14 20:25:25

注释

PHP 5.2 之后的版本中，可以使用 Unix 时间戳作为构造函数的参数生成新的DateTime对象，例如：

PHP 5.2 之后的版本中，DateTime::setTimestamp()替代方案

以上例程的输出类似于：

1171502725 = 2007-02-14 20:25:25

• DateTime::getTimestamp() Gets the Unix timestamp

It should be noted above, be careful when manipulating the DateTime object with unix timestamps.
In the above examples you will get varying results dependent on your current timezone, method used, and version of PHP.
One would expect all of the examples above to perform the same as setTimestamp() or date('H:i', $timestamp); would.

Set timestamp from UTC timezone use UTC timezone

To convert the above to use the current timezone simply use

Set the timestamp from UTC timezone use current timezone

Set the timestamp from current timezone use current timezone 

When you need to manipulate a unix timestamp like field (seconds since 1970-01-01) that may be greater than the drop dead date of 2038-01-19. 

When the exact time is important then it is important to note the difference between this and the UnixTimeStamp. The function will change the timestamp if necessary to take into account the daylight savings time.
e.g. Working with the 'Europe/London' timezone and setting the DateTime object to a timestamp of 1288486753 will result in the function automatically altering it to 1288490353.
This is because it is taking the fall time instead of the summer time (they will both be Sun, 31-Oct-2010 01:X:Y (I didn't check the hour and minute)).
Sincerely,
Aouie

If your PHP version is lower than 5.3 then you can use this class to be able to use the functions "setTimestamp" and "getTimestamp":
