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
configuration uses.
