This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
Availability
JavaScript 1.0; JScript 1.0; ECMAScript v1
Synopsis
date.getTimezoneOffset( )Returns
The difference, in minutes, between
Greenwich Mean Time (GMT) and local time.
Description
getTimezoneOffset( ) returns the number of minutes
difference between the GMT or UTC time and the local time. In effect,
this function tells you what time zone the JavaScript code is running
in and whether or not daylight savings time is (or would be) in
effect at the specified date.
The return value is measured in minutes, rather than hours, because
some countries have time zones that are not at even one-hour
intervals.
