document.write(new Date(1988,11,1,0,0,0).toString()); 
should return Nov 1 1998, but I get (in Linux):
Wed Nov 30 1988 23:00:00 GMT-0300 (ART) 
In Windows works OK (it returns Thu Dec 01 1988 00:00:00 GMT-0300 (SA Eastern
Standard Time). 



Reproducible: Always
Steps to Reproduce:
1. Open a text editor and write: <HEAD>
</HEAD>
<BODY>
<SCRIPT>
document.write(new Date(1988,11,1,0,0,0).toString());
</SCRIPT>
</BODY>

2. Save this as html
3. Open that page with FF 1.0 under Linux.

Actual Results:  
Wed Nov 30 1988 23:00:00 GMT-0300 (ART)

Expected Results:  
Thu Dec 01 1988 00:00:00 GMT-0300 (SA Eastern Standard Time)
If you put document.write(new Date(1988,11,1)) you get the same as reported
(diferent dates in diferent platforms).
This Error Also ocurrs on Mozila 1.7.5 Suite and Firefox 1.0.1 Both on Linux
(XOrg 6.8.1 - Krnl 2.4.29).

On Windows works fine.

On Netscape Browsers also works fine.

Simple Script to reproduce the error:

<html>
<script>
	alert(new Date(2005,9,14));
	alert(new Date(2005,9,15));
	alert(new Date(2005,9,16));
</script>
</html>

The 09/16/2005 on 3rd alert appears like 09/15/2005.

For the 2004 year works fine.

Firefox v1.0.6 for Windows XP

JavaScript 

	var today = new Date();
	var thisYear = today.getYear();

Returns 105 instead of 2005

TRy this to solve the Year Format Problem using thsi code instead:
<script language =Javascript>
var today = new Date();
var thisYear = today.getYear();
if (thisYear<1900)
{
thisYear=(thisYear+1900);
}
document.write (thisYear);
</script>

The last two comments have nothing to do with this bug as reported.  Don't use getYear, use getFullYear.  End of story (this was settled in ECMA-262 Edition 1 before y2k; IE did something other than what that spec advises in its informative annex for getYear; we can't fix IE at this point, and we should not try following it into the weeds here).

Can someone with canconfirm privs confirm this bug?

/be
Can't confirm this in windows or linux FF 1.0.7 with PST. I can't change the timezeone on my test linux box so someone else with linux will have to test this.

Reporter, is this still a problem in FF 1.5?
