sunrise/sunset sorts incorrectly, but the BCE years already break this, so 
it seems somewhat secondary.  We could pretend "AM/PM" represent 
ante-/post-median rather than meridian.

BCE is important for timelines, e.g. encoding Bishop Ussher's timeline
from 4004 BCE.

Vigils, Matins, Lauds, Terce, Sext, None, Vespers, & Compline are the
medieval prayer times.  Lauds/Vespers would probably be more precise for 
both Sunrise/Sunset and AM/PM, but since no one knows those, I'm not 
recommending them.

This sounds good to me.

One issue I forgot to mention is the practice, with ISO dates of starting 
the hour with capital T to mark the transition from date to time, which we 
could also adopt, e.g. CE.2003.05.24.T09.14 .  If we're doing a work keyed 
to times only, it helps us figure out that T09.14 refers to HH.mm rahter 
than MM.DD.
