> The o.a.c.lang.time.DateUtils should have functions for comparing dates and Calendars to only second precision instead of millisecond. The motivation for this is comparison of dates and Calendars in objects both before and after the objects have been committed to and retrieved from a database. In theory the objects should be equal if 'equals' is run on them, but in practice they are not because the date fields do not have exactly the same millisecond values after they've been persisted to a database since times in many databases are only maintained to second-level precision (and without TimeZone information in many cases, to boot!)
