function isDate (year, month, day)
{

	// This is an interesting way to do validation of dates!

	// First, decrement the given month;
	// since humans think in base ONE and
	// JavaScript dates for months think in base ZERO.
	//      Human month range : 1 - 12
	// JavaScript month range : 0 - 11
	month--;  

	// Then, create a new JS Date Object based upon given values.
	// NOTICE: This will convert 2/32/2000 to 3/3/2000
	//         JavaScript 'helps' you like this.
	var objTempDate = new Date(year,month,day);

	// Now, tear that new Data Object apart and see if the
	// values it gives back matches what we gave it.
	return	( ( objTempDate.getFullYear() == year  ) &&
			  ( objTempDate.getMonth()    == month ) &&
			  ( objTempDate.getDate()     == day)  )  ? true : false

	// Very nice method Dan!
}

function isTime (intHour, intMinute, intSecond)
{
	// Baased upon:   Dan Osborne <dano at specialist.co.uk>

	return	( ( objTempTime.getHours()   == intHour   )  &&

}
