Year 2000 Problem
Question: Is JavaScript code vulnerable to the Year 2000 problem?
Answer:
You can write your code so as to make sure that
it will not suffer from "millennium bugs" even if run on
older browsers. However, without special precautions,
JavaScript code can be vulnerable to the Year 2000 problem.
To avoid "millennium bugs", take into account the following:
- in most browsers, the
Date.getYear() method returns the full four-digit year
for the year 2000 and all subsequent years
- in some old browsers (for example, Internet Explorer 3.0)
this method returns the year minus 1900 for all years.
The following code fragment sets the correct four-digit
year in all browsers:
theDate = new Date();
theYear = theDate.getYear();
if (theYear<1900) theYear=theYear+1900;
