The JScript version 5.7 Date object reports time in standard time instead of in daylight saving time after you apply the updates in Microsoft Knowledge Base articles 928388 and 932590 on a computer that is running Windows XP or Windows Server 2003

Consider the following scenario. You take the following actions on a computer that is running Microsoft Windows XP or Microsoft Windows Server 2003:

1. You install the 2007 time zone update for Microsoft Windows operating systems that is documented in the following Microsoft Knowledge Base article:
   928388

   (http://support.microsoft.com/kb/928388/ )

   2007 time zone update for Microsoft Windows operating systems
2. You install the C run-time (CRT) update that is documented in the following Microsoft Knowledge Base article:
   932590

   (http://support.microsoft.com/kb/932590/ )

   FIX: Windows-based applications that use the TZ environment variable may not work as expected because of changes to DST
3. You set the TZ environment variable.

In this scenario, when you create a custom application that uses the JScript version 5.7 Date object, the time is reported incorrectly for dates that are between the second Sunday in March and the first Sunday in April for the year 2007. Instead of the time being reported in daylight saving time, the time is reported in standard time. For example, for March 30, 2007, the JScript Date object reports time in standard time instead of in daylight saving time.

Note JScript version 5.7 is included with Windows Vista. Additionally, when you install Internet Explorer 7 on a computer that is running Windows XP with Service Pack 2 (SP2), Windows XP Professional x64 Edition, or Windows Server 2003 SP1, JScript version 5.7 is installed.
