ZConfig supports two datatypes for time deltas:
"time-interval" is a number of seconds, provided as a float. In a
configuration file, a slightly more readable expression is used. For
example, "4d 3h 2m 1s" means "4 days 3 hours 2 minutes 1 second".
"timedelta" is a datetime.timedelta value. The syntax in the
configuration file is the same as for time-interval.
Neither allows specifying a negative delta value; they're really about
an interval rather than a delta. Fortunately, that covers most
