MessagePack spec version 2.1 has Timestamp type

https://github.com/msgpack/msgpack/blob/master/spec.md#formats-timestamp

Timestamp extension type is assigned to extension type -1. It defines 3 formats: 32-bit format, 64-bit format, and 96-bit format.

Is there a PR for this? I'd love to have this new type in msgpack-lite

I'm coming almost close: Timestamp for 64-bit time_t, nanosecond precision and strftime

I could rarely find any other msgpack libraries which support the new ext type -1.
Here is a C library not merged yet though.

@mattbishop do you know any library that have tests for the type -1?

I don't know of any but other lib authors will follow your lead. Have you done beta releases of Msgpack before? Might be a good way to get the feature into the public space and trigger others to add their own implementations.
