Hi,

Can anybody suggests on how to get the Business Hours:Min:Sec from two dates.

Thanks

Sorry, wrong forum - this is a Java question.

Venkat,

My apologies - I misunderstood what you were asking about.

As you probably know, BusinessCalendar has an add function, but not a subtract. The calendar package is not documented at all - not even any significant comments.

I think you'll want to use BusinessCalendar.findDayPart to get the beginning and end time-segments for your interval, add the deltas for each end, and then sum the durations of all the intervening DayParts. It doesn't look too hard. You might consider contributing it back, especially if you write test code to make sure you got it right.

Ed,

Thanks for the suggestion. I did some basic implemenation. Though it is not 100% complete , good for some body to start with. At this point the requirement was dropped from the project. I will update on this once I get chance to work again.

Following is the code:


import java.util.Calendar;
import java.util.Date;

public class TestCalendar {
static int deltaHour = 0;
static int deltaMinute = 0;
static boolean flag= true;
static boolean isFirstTime= true;

public static void main(String args[]){
System.out.println("Current Time ..."+new Date());
//findBusinesstime();
Calendar calendar = BusinessCalendar.getCalendar();
calendar.set(Calendar.YEAR, 2007);
calendar.set(Calendar.MONTH, Calendar.JANUARY);
calendar.set(Calendar.DAY_OF_MONTH, 25);
calendar.set(Calendar.HOUR_OF_DAY, 13);
calendar.set(Calendar.MINUTE, 15);
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MILLISECOND, 0);
Date startDay = calendar.getTime();
System.out.println(startDay);

Calendar calendar2 = BusinessCalendar.getCalendar();
calendar2.set(Calendar.YEAR, 2007);
calendar2.set(Calendar.MONTH, Calendar.JANUARY);
calendar2.set(Calendar.DAY_OF_MONTH, 27);
calendar2.set(Calendar.HOUR_OF_DAY, 13);
calendar2.set(Calendar.MINUTE, 15);
calendar2.set(Calendar.SECOND, 0);
calendar2.set(Calendar.MILLISECOND, 0);
Date endDay = calendar2.getTime();
System.out.println(endDay);

addHours("D:/workspace/SLA");

}
public static String getBusinessHours(BusinessCalendar businessCalendar,Date startDate, Date endDate){
DayPart dayPart = null;

Calendar calendar = BusinessCalendar.getCalendar();
calendar.setTime(startDate);
int hour = calendar.get(Calendar.HOUR_OF_DAY);

System.out.println("deltaHour------->"+deltaHour);

if(compareDates(startDate,endDate)== 1){ // First before day
if (!businessCalendar.isHoliday(startDate)) {
