MongoDB\BSON\Timestamp::getTimestamp
(mongodb >=1.3.0)
MongoDB\BSON\Timestamp::getTimestamp — Returns the timestamp component of this Timestamp
説明
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.

戻り値
Returns the timestamp component of this Timestamp.
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.
