You are welcome,

if you convedrt a Date into a long (mSec) you can add as you like.
If you convert back to a Date it will probably not be the same Date (datum).
So, you can!
Examples?

// Get a calendar
Calendar c = Calendar.getInstance() ;
// Set the time to now
c.setTimeInMillis( System.currentTimeMillis() ) ;
// Add four hours
c.add( Calendar.HOUR, 4 ) ;
// add 30 mins
c.add( Calendar.MINUTE, 30 ) ;
// get the date back
Date newDate = new Date( c.getTimeInMillis() ) ;

That was fast...  
I've tried the codes Tim but I am encountering an error in setTimeInMillis...

setTimeInMillis has protected access in java.util.Calendar

May I ask how to resolve this...?

Thanks again... =)

It does?

What JDK you using?  It's public in 1.4

Hmmm...

Try:

c.setTime( new Date() ) ;

instead...  that will do the same thing :-)
