235837 - Bad handling of years after 2000 in getYear() function

Status: RESOLVED DUPLICATE of bug 22964

(Core :: JavaScript Engine, defect)

Description

[Phate.007]

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

Mozilla badly treats years after 2000 in getYear() function. In year 2004 it
says, that it is year 104.

I must manually add number 1900 to all years, which are represented by smaller
number than 1000.

Reproducible: Always
Steps to Reproduce:




// JavaScript Document
lastmod = new Date(document.lastModified);
lastmoddate = Date.parse(lastmod);
month = lastmod.getMonth();
month++;
seconds = lastmod.getSeconds()
minutes = lastmod.getMinutes()
hours = lastmod.getHours()
years = lastmod.getYear();

if (seconds < 10){
	seconds = "0" + seconds
}

if (minutes < 10){
	minutes = "0" + minutes
}

if (hours < 10){
	hours = "0" + hours
}

//this if statement must I add in order to have accurate results in Mozilla
if (years < 1000){
	years = years + 1900
}

lastmodif = lastmod.getDate() + "." + month + "." + years + " v " + hours + ":"
+ minutes + ":" + seconds;

if(lastmoddate == 0){
  document.write("Unknown date of last modification")
  } else {
    document.write("Last modification: " + lastmodif)
}

getYear() was deprecated. Use getFullYear() instead of getYear().
See bug 45764 comment 4 for further info.
