[xquery-talk] Date Arithmetic

[Michael Kay]

See:

http://www.w3.org/TR/xpath-functions/#func-subtract-dateTimes-yielding-d
ayTimeDuration

http://www.w3.org/TR/xpath-functions/#func-subtract-dateTimes-yielding-y
earMonthDuration

But don't necessarily expect to find these functions implemented; this
area of the spec hasn't been all that stable between drafts.
