MongoDB\BSON\Timestamp::getIncrement — Returns the increment component of this Timestamp
The increment component of a Timestamp is its least significant 32 bits, whichs denotes the incrementing ordinal for operations within a given second. This value is read as an unsigned 32-bit integer with big-endian byte order.
Nota: Debido a que le tipo de entero de PHP es con signo, algunos valores devueltos por este método podrían aparecer como enteros negativos en plataformas de 32 bits. El formateador "%u" de sprintf() se puede usar para obtener una representación de string del valor decimal sin signo.
Esta función no tiene parámetros.
Returns the increment 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.
