Durationpublic class Duration extends Object | According to RFC2445, durations are like this:
WEEKS
| DAYS [ HOURS [ MINUTES [ SECONDS ] ] ]
| HOURS [ MINUTES [ SECONDS ] ]
it doesn't specifically, say, but this sort of implies that you can't have
70 seconds. |

its parsing, for better or for worse)
