SYMPTOMS
Because the Olympic Games are scheduled to be held in September, 2000 in Sydney, Australia, several Australian states (New South Wales, Victoria, Australian Capital Territory, and Tasmania) have moved the daylight saving time transition start date forward two months (for the year 2000 only), from the last Sunday in October to the last Sunday in August.

Programs that are built by using Microsoft Collaboration Data Objects (CDO), such as Microsoft Outlook Web Access (OWA), may not correctly reflect this change to the daylight saving time transition date because CDO maintains an internal table to track time zone information. This table is not updated with changes that are made to the operating system time zone.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this hotfix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:

Component: CDO



STATUS
Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5.



MORE INFORMATION
After you install this fix, applications that are written using CDO (such as the AutoAccept event script) can be updated with the new Sydney year 2000 time zone.

You need to modify part of the OWA Active Server Pages (ASP) code to enable OWA users to use the new time zone. In particular, you need to modify the Set.asp file in the Webdata\Usa\Options folder so the new time zone can be selected on the Options page. The following is an example of the modifications that need to be made to the Exchange Server 5.5 Service Pack 3 version of the Set.asp file.

At around line 151, change the following array definition

Function AmToIdx(n) Dim A        '1   2   3   4   5   6   7   8   9  10 11 12 13 14 15 16  17  18  19  20  21  22  23  24  25  26  27  28  29  30  31  32  33  34  35 36 37 38 39  40  41  42  43  44  45  46  47  48  49  50  51 A = Array(-1, 20, 24, 23, 22, 28, 25, 26, 16, 13, 11, 7, 6, 4, 3, 2, 1, 50, 45, 43, 42, 41, 39, 37, 34, 33, 31, 30, 15, 19, 18, 21, 17, 14, 12, 10, 9, 8, 5, 0, 49, 48, 47, 46, 44, 40, 38, 36, 35, 27, 29, 32) AmToIdx = A(n) End Function to the following Function AmToIdx(n) Dim A        '1   2   3   4   5   6   7   8   9  10 11 12 13 14 15 16  17  18  19  20  21  22  23  24  25  26  27  28  29  30  31  32  33  34  35 36 37 38 39  40  41  42  43  44  45  46  47  48  49  50  51  52 A = Array(-1, 20, 24, 23, 22, 28, 25, 26, 16, 13, 11, 7, 6, 4, 3, 2, 1, 50, 45, 43, 42, 41, 39, 37, 34, 33, 31, 30, 15, 19, 18, 21, 17, 14, 12, 10, 9, 8, 5, 0, 49, 48, 47, 46, 44, 40, 38, 36, 35, 27, 29, 32, 51) AmToIdx = A(n) End Function The preceding changes provide for a fifty-second entry in the array &quot;A&quot; with a value of &quot;51&quot; as the newly referenceable time zone.

At around line 451, after the following lines (GMT+11:00) Magadan, Soloman Islands., New Caledonia (GMT+12:00) Fiji Islands, Kamchatka, Marshall Islands. (GMT+12:00) Wellington, Auckland add a new line as follows (GMT+10:00) Canberra, Melbourne, Sydney, Hobart (Year 2000 only) This addition makes the new time zone available from the list on the OWA Options page. After users select this new time zone, subsequent appointments are created correctly.
