d d Z d S) TimestampaR Timestamp represents the Timestamp extension type in msgpack.
When built with Cython, msgpack uses C methods to pack and unpack `Timestamp`. When using pure-Python
msgpack, :func:`to_bytes` and :func:`from_bytes` are used to pack and unpack `Timestamp`.
This class is immutable: Do not override seconds and nanoseconds.

:param int seconds:
Number of seconds since the UNIX epoch (00:00:00 UTC Jan 1 1970, minus leap seconds).
May be negative.
:param int nanoseconds:
Number of nanoseconds to add to `seconds` to get fractional time.
Maximum is 999_999_999. Default is 0.
Note: Negative times (before the UNIX epoch) are represented as negative seconds + positive ns.
