How the product handles dates:
Dates are stored internally the same as they are for the Win32 FILETIME structures. The FILETIME structure is a 64-bit value.
Two-digit shortcut handling:
Some 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.
Internet Explorer assumes that 80 û 99 are 1980 to 1999 and 00 û 35 are 2000 to 2035 and 36 û 70 are 2035.
Common date usage errors:
Independent of Internet ExplorerÆs handling of dates, web page HTML content, JSCRIPT, java applets, server scripts, or controls may have potential year 2000 issues.
Also note: when viewing dates in Internet Explorer for history, true web integration, the display of 4-digit years in Windows or Windows NT needs to be enabled through the regional settings in control panel.
If you are testing certificates in Internet Explorer that are not yet valid, Internet Explorer displays a message that they are expired.
Outlook Express Issue (software update is not part of Internet Explorer 4.01)
If Outlook Express (OE) 4.01 receives an IMAP mail message or a News message with a 2-digit year as the sent date, the date can be misinterpreted under certain conditions. If the 2-digit year is anything other than 99, OE will assume the century value is the same as the current century. If the current year is 2000, and a 2-digit date is received as 97, then the year will be interpreted as 2097. However, there is one special case when different logic is applied. If the 2-digit year 99 is received and the current year is a multiple of 100 (e.g. 2000), the year will be interpreted as the current year plus 98 (e.g. 2098).
For more information and the software update for this issue, please review Knowledge Base Articles Q237823 or Q237824.
A software update is available for this issue. (There is a separate update if you are running Outlook Express 4.01.) The software update is found here.
Testing guidelines and recommendations:
Web sites or web-based applications need to have Internet Explorer, the web server, and if applicable, proxy server test all transition to and operate in the year 2000. For example, depending on your web and proxy server, it may use a 2-digit year in its HTTP/1.0 headers. While Internet Explorer has been 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. Note: If you are testing certificates in Internet Explorer that are not yet valid, Internet Explorer displays a message that they are expired.
- Code Download: If you are testing certificates in Internet Explorer that are not yet valid, Internet Explorer displays an incorrect message that they are expired.
- File Download: Verify of proper download of any files referred to by your site.
- Search: Verify that search bar works for your preferred search provider.
- Subscriptions: Internet Explorer 5 provide for publisher-scheduled updates and expiration for content. Verify proper update of subscribed sites.
- Autoconfiguration: The Internet Explorer Administration Kit allows for downloading of new settings and restrictions maintained by an administrator on a server. Options for autoconfiguration include updating settings by date and by a timeout value.
In addition, contact your web server and proxy server vendor for their Year 2000 status and recommendations.
Also, 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, JSCRIPT, java applets, server scripts, or controls. | |
