new Timestamp(low, high)
This type is for INTERNAL use in MongoDB only and should not be used in applications.
The appropriate corresponding type is the JavaScript Date type.
Defines a Timestamp class for representing a 64bit two'scomplement
integer value, which faithfully simulates the behavior of a Java "Timestamp". This
implementation is derived from TimestampLib in GWT.
Constructs a 64bit two'scomplement integer, given its low and high 32bit
values as signed integers. See the from* functions below for more
convenient ways of constructing Timestamps.
The internal representation of a Timestamp is the two given signed, 32bit values.
We use 32bit pieces because these are the size of integers on which
Javascript performs bitoperations. For operations like addition and
multiplication, we split each number into 16bit pieces, which can easily be
multiplied within Javascript's floatingpoint representation without overflow
or change in sign.
In the algorithms below, we frequently reduce the negative case to the
positive case by negating the input(s) and then postprocessing the result.
Note that we must ALWAYS check specially whether those values are MIN_VALUE
(2^63) because MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
a positive number, it overflows back into a negative). Not handling this
case would often result in infinite recursion.
