When I use the below code, I get "9/20/2006 1:07 AM".  I checked my system time and all is well.  It's October, so why is it returning 9?

function insertAtCursor(myField) {
  var myValue;
  var currentDate = new Date();
  var day = currentDate.getDate();
  var month = currentDate.getMonth();
  var year = currentDate.getFullYear();
  myValue = month + "/" + day + "/" + year + " ";
 
  var currentTime = new Date();
  var hours = currentTime.getHours();
  var minutes = currentTime.getMinutes();

  var suffix = "AM";
  if (hours >= 12) {
  suffix = "PM";
  hours = hours - 12;
  }
  if (hours == 0) {
  hours = 12;
  }

  if (minutes < 10)
  minutes = "0" + minutes;

  myValue += hours + ":" + minutes + " " + suffix;
if (document.selection) {
myField.focus();
sel = document.selection.createRange();
sel.text = myValue;
}
else if (myField.selectionStart || myField.selectionStart == '0') {
var startPos = myField.selectionStart;
var endPos = myField.selectionEnd;
myField.value = myField.value.substring(0, startPos)
+ myValue
+ myField.value.substring(endPos, myField.value.length);
} else {
myField.value += myValue;
}
}

The javascript components all start from 0. so january would return '0' and not 1. Just a traditional way how array's behave. the index starts from 0, instead of 1

this should help

Thanks harshgrover.  I use arrays a lot and I understand starting from 0, but that's just stupid.  Who would make a date function to get the current month and start it from 0?  The least they could do is be consistent and have getDate() act the same way.
naw, i might be wrong, but i thought all the calendars in java behave the same, whether it is GregorianCalendar, java.util.Date etc. if you want to get the number of the month, they would all return 0 for January :)...i guess we programmers dont really care a lot about how things function in the real world ;)
