Examples of org.clapper.util.text.Duration

org.clapper.util.text.Duration
This class contains methods to parse and format time durations. A time duration is a string like "1 second", "10 minutes", "360 days", "4 hours, 30 seconds". This class can
- parse strings of that form to produce delta values (long integers)
- produce such strings by subtracting two dates or subtracting a date and a duration,
- add a duration to or subtract a duration from a Date, producing a new Date
The parser recognizes the following intervals and synonyms. (The names are in English; if resource bundles for other languages exist, the names will obviously be different.)
- milliseconds (millisecond, ms)
- seconds (seconds, sec, secs)
- minutes (minute, min, mins)
- hours (hour, hr, hrs)
- days (day)
- weeks (week)
Years and months are omitted to avoid the irregularity of leap years and different month lengths, respectively. Weeks are honored on input only. @version $Revision: 6687 $ @since org.clapper.util version 2.4.1 @author Copyright © 2004-2007 Brian M. Clapper
