Date	ceiling(final Object date, final int field) Gets a date ceiling, leaving the field specified as the most significant field. For example, if you had the date-time of 28 Mar 2002 13:45:01.231, if you passed with HOUR, it would return 28 Mar 2002 14:00:00.000.
long	getFragmentInDays(final Date date, final int fragment) Returns the number of days within the fragment.
long	getFragmentInDays(final Calendar calendar, final int fragment) Returns the number of days within the fragment.
long	getFragmentInHours(final Date date, final int fragment) Returns the number of hours within the fragment.
long	getFragmentInHours(final Calendar calendar, final int fragment) Returns the number of hours within the fragment.
