I'm working on a scheduler, and my first inclination was to use tinterval
(since I happen to have data available in YYYY-MM-DD HH:MM-HH:MM anyway).
After some trial and error, I've finally discovered the && overlap operator
(it's mentioned in the regression tests but not in the manual), which I
need.
However, I also need to know how long a tinterval is. The | is nice for
getting the start time in a tinterval, but I can't figure out how to get
the stop time, or an interval out of tinterval. Is there a way?
Barring that, how could I efficiently use a timestamp/interval pair to
prevent overlaps (better, overlaps are ok if a certain resource is shared).
It seems that tinterval is deprecated, but it comes very close to fitting my
needs.
