I did have one somewhat trivial thought. I generally prefer durations and intervals expressed as datetime.timedeltas myself, because they convey their meaning without having to look it up docs (is that number value a number of seconds? milliseconds? minutes?). There might even be a zcml built in for schema field for that; I believe I remember that there is in ZConfig.
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. -Fred -- Fred L.
