Support for Motion Imagery Standards Profile (MISP) Time System #194

Open bradh opened 2 years ago

bradh commented 2 years ago

The Motion Imagery Standards Board (MISB) publishes a number of standards based around the MISP Time System. Its like POSIX, but with SI Seconds.

The documents are public, and are available at https://nsgreg.nga.mil/misb.jsp

The key documents are the Motion Imagery Handbook (Chapter 6), ST 0603 and ST 0604.

The calculations are pretty simple (at least for TAI - it'll be a fixed offset).

Would addition of org.threeten.extra.scale.MispInstant (or some similar name) and supporting conversions likely be reasonable?

Seems reasonable if it follows the design and style of the existing time scales
