MongoDB\BSON\UTCDateTime::toDateTime — Returns the DateTime representation of this UTCDateTime
此函数没有参数。
Returns the DateTime representation of this UTCDateTime. The returned DateTime will use the UTC time zone.
示例 #1 MongoDB\BSON\UTCDatetime::toDateTime() example
<?php
$utcdatetime = new MongoDB\BSON\UTCDateTime(1416445411987);
$datetime = $utcdatetime->toDateTime();
var_dump($datetime->format('r'));
var_dump($datetime->format('U.u'));
var_dump($datetime->getTimezone());
?>以上示例的输出类似于：
string(31) "Thu, 20 Nov 2014 01:03:31 +0000"
string(17) "1416445411.987000"
object(DateTimeZone)#3 (2) {
["timezone_type"]=>
int(1)
["timezone"]=>
string(6) "+00:00"
}
