MongoDB\BSON\UTCDateTime::__construct — Construct a new UTCDateTime

### Descripción

final public MongoDB\BSON\UTCDateTime::__construct(int|float|string|DateTimeInterface|null `$milliseconds` = `null`)

### Parámetros

`milliseconds` (int|float|string|DateTimeInterface|null)

  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 int. 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.

  If this argument is `null`, the current time will be used by default.

### Errores/Excepciones

PECL mongodb 1.2.0 | The `milliseconds` argument is optional and defaults to `null` (i.e. current time). The argument also accepts a DateTimeInterface, which may be used to derive the number of milliseconds since the Unix epoch. Previously, only int, float, and string types were accepted.

### Ejemplos

Ejemplo #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));
?>`

El resultado del ejemplo sería algo similar a:

    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"
    }
