Examples: 

new Calendar( new Date( "2002/02/28 13:45" ).isSameDay( new Calendar( new Date( "2002/02/28 06:01" ) ) );
would return true. 
new Calendar( new Date( "2002/02/28 13:45" ).isSameDay( new Calendar( new Date( "2002/02/12 13:45" ) ) );
would return false. 
new Calendar( new Date( "2002/02/28 13:45" ).isSameDay( new Calendar( new Date( "1970/02/28 13:45" ) ) );
would return false. 
 var cal1 = new Calendar( new Date( "2002/02/28 02:00" );
 cal1.setTimeZone( "Etc/GMT+1" );
 var cal2 = new Calendar( new Date( "2002/02/28 00:00" );
 cal2.setTimeZone( "Etc/GMT+1" );
 cal1.isSameDay( cal2 );
would return false since the time zone is applied first which results in comparing 2002/02/28 01:00 for cal1 with 2002/02/27 23:00 for cal2.

Parameters:

 var cal2 = new Calendar( new Date( "2002/02/28 00:00" );
 cal2.setTimeZone( "Etc/GMT+1" );
 cal1.isSameDayByTimestamp( cal2 );
would return true since the time zone is not applied first which results in comparing 2002/02/28 02:00 for cal1 with 2002/02/28 00:00 for cal2.

Parameters:
other - the calendar to compare against this calendar.
isSet
