Chris,

I term page as the physical xhtml file that represents the stuff

Period is field-based, and therefore deals with non-linear time changes like
daylight savings time. Periods can be converted to millisecond durations
based on standard field durations (60 seconds == 1 minute, etc) if needed,
so it's a superset of the current functionality of TimeSpan.

That's pretty much my take. The whole Java Calendar/Date/Timezone impl is
poorly designed, hence Joda Time.

I could do that, but I would still have an ambiguous definition of now,
