MongoDB\BSON\Timestamp::getTimestamp — Returns the timestamp component of this Timestamp

### 説明

final public MongoDB\BSON\Timestamp::getTimestamp ( void ) : int

The timestamp component of a Timestamp is its most significant 32 bits, which denotes the number of seconds since the Unix epoch. This value is read as an unsigned 32-bit integer with big-endian byte order.

> 注意: Because PHP's integer type is signed, some values returned by this method may appear as negative integers on 32-bit platforms. The "%u" formatter of sprintf() may be used to obtain a string representation of the unsigned decimal value.

### パラメータ

この関数にはパラメータはありません。

### 返り値

Returns the timestamp component of this Timestamp.

警告

On 32-bit systems this method may return a negative number. Although the increment and timestamp parts of the BSON timestamp type consists of two unsigned 32-bit values, PHP can not represent these on 32-bit platforms.
