Class SafeCalendarUtils

java.lang.Object
  mseries.utils.SafeCalendarUtils

public class SafeCalendarUtils
extends Object

Class created to "work-around" an apparent bug with sun.util.BuddhistCalendar (hardcoded to be returned by Calendar.getInstance() calls for the Thai locale (language)). The bug causes the Calendar date to become incorrect (e.g. 1998 + 5 years becomes 1460) whenever a .add(...) call forces a year change.

                                        int amount)

Creates a temporary GregorianCalendar, sets its time, uses it for the addition, and then sets the modified time to the passed in Calendar. Note: This convenience performs a .add(...) call (as opposed to a .roll(...) call) on the Calendar.

Parameters:

cal - The calendar to be modified by adding the amount of field to it

field - A constant from the Calendar class (DAY, MONTH, etc.)

amount - The amount of field to add to the calendar.
