Product Details |
How the product handles dates:
Dates are stored internally as a 32-bit integer in Macintosh operating system time. The structure is a 32-bit value that represents the number of seconds since January 1, 1904.
Two-digit shortcut handling:
Microsoft Internet Explorer 4.5 for Macintosh interprets dates entered with a 2-digit shortcut to mean the in the following way:
Two-Digit years 00 through 49 are interpreted as 2000 through 2049.
Two-Digit years 50 through 99 are interpreted as 1950 through 1999.
Some web sites using older web servers may use HTTP/1.0 headers that have a 2-digit date representation for the year. Web authors may also use a 2-digit year representation for expiration date of cookie data.
Internal representation of the date range is 1904 to year 2035. If a web server communicates a 2-digit year in its HTTP/1.0 header, Internet Explorer will interpret it as mentioned above and will return the 4-digit representation to the server. If the server requires 2-digit representation, Internet Explorer will send it in 2-digit representation. Headers with a 4-digit year, or headers containing 2-digit years will be interpreted in accordance with the rules described above.
Common date usage errors:
Independent of Internet ExplorerÆs handling of dates, web page HTML content, server certificates, JSCRIPT, Java applets, server scripts, or controls may have potential year 2000 issues.
The Jscript method .getYear() returns a 2-digit string for years within the operational range up to 1999. The method returns a 4-digit string for years within the operational range from 2000. Web authors can use the method .getFullYear(), which returns 4-digit dates.
The X.509 specification for certificates requires the valid date range to be described using two-digit years through the year 2049. Four-digit year format is not to be used until 2050 and later. These issues, combined with the fact than many secure certificates are set to expire at midnight, December 31, 1999 should be considered by web site administrators to prevent interruption of service to their customers.
Testing guidelines and recommendations:
Tests of web sites or web-based applications for the year 2000 need to have Internet Explorer, the web server, and if applicable, proxy server transition to operate in the year 2000. For example, some web and proxy server may use a 2-digit year in its HTTP/1.0 headers. While the Internet Explorer team has tested operation with popular web servers and proxy servers, verification of Internet Explorer should include testing of the below items within your corporate environment.
- Authentication: If you use a secured site and/or SSL connections, verify proper authentication of authorized users, denial of others, and proper operation.
- File Download: Verify proper download of any files referred to by your site.
- Search: Verify that search bar works for your preferred search provider.
- History: Internet Explorer organizes sites you have recently visited by "today", "yesterday", and previous weeks.
- Subscriptions: Internet Explorer 4 provides for publisher-scheduled updates and expiration for channel content. Verify proper update of subscribed sites.
In addition, contact your web server and proxy server vendor for their year 2000 status and recommendations.
Some potential year 2000 issues may be content-specific. You should ensure that interactive sites can handle the year 2000 in their web page HTML content, cookies, server certificates, JSCRIPT, Java applets, server scripts, or controls.
