MongoDB\BSON\Timestamp::getTimestamp

Returns the timestamp component of this Timestamp

説明

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

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.

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.
