MongoDB\BSON\UTCDateTime::__construct — Construct a new UTCDateTime
$milliseconds = NULL
] )
milliseconds (integer|float|string|DateTimeInterface)Number of milliseconds since the Unix epoch (Jan 1, 1970). Negative values represent dates before 1970. This value may be provided as a 64-bit integer. For compatibility on 32-bit systems, this parameter may also be provided as a float or string.
If the argument is a DateTimeInterface, the number of milliseconds since the Unix epoch will be derived from that value. Note that in versions of PHP versions before 7.1.0, DateTime and DateTimeImmutable objects constructed from the current time did not incorporate sub-second precision.
If this argument is NULL, the current time will be used by default.

Example #1 MongoDB\BSON\UTCDateTime::__construct() example
<?php
var_dump(new MongoDB\BSON\UTCDateTime);
var_dump(new MongoDB\BSON\UTCDateTime(new DateTime));
var_dump(new MongoDB\BSON\UTCDateTime(1416445411987));
?>
以上例程的输出类似于：
object(MongoDB\BSON\UTCDateTime)#1 (1) {
["milliseconds"]=>
string(13) "1484852905560"
}
object(MongoDB\BSON\UTCDateTime)#1 (1) {
["milliseconds"]=>
string(13) "1484852905560"
}
object(MongoDB\BSON\UTCDateTime)#1 (1) {
["milliseconds"]=>
string(13) "1416445411987"
}
