Also, please check if other applications are behaving in this manner. Hopefully this will not sound like I'm pointing fingers, but I have seen several comments within Microsoft blogs that indicate that the DST patch for Windows encounters this issue - namely that the DST "fix" is not year dependant, so that data from previous years picks up the DST schedule for 2007. See: http://www.jnbridge.com/blog/?p=23 "There's a very interesting problem with Microsoft's DST patch for Windows that you should be aware of, since it can impact date conversion results when mapped date proxies are used. The patch applies the new rules for whether date and time are daylight savings time without regard to year. This means that if you ask .NET whether a given DateTime in the past is DST, it will apply the new rules even if the date would have been standard time under the old rules."
and http://blogs.msdn.com/michkap/archive/2007/02/05/1606868.aspx "Apparently we were naïve, as now historic times are calculated incorrectly due to Windows inability to calculate the correct DST times from previous years, including 2006! You can try it for yourself, by changing the system clock to March 13th 2006 on a Windows XP machine (or 2000 machine with manual registry patch as suggested in KB914387). Vista gets it right, but as that represents < 0.1% of our install base it's not much consolation at the moment." Again, I'm not saying that this is the case, but it's something to test for - namely whether the issue you are seeing was caused by the AR System patch or happened when you loaded the OS and/or Java patches. Since AR System in general uses the Operating System for DST information except for the Mid-Tier, web services and import/export; DST 2007 issues seen in other parts of AR System are potentially linked to the DST changes in the Operating System itself.

I've just installed Patch 20 for both, and am in the process of doing some preliminary testing. Remedy seems to be applying the revised schedule for 2007 for earlier years as well. For example, it seems to be seeing March 20th 2007 as Eastern Daylight Time (EDT), which is correct. But it seems to see March 20th 2006 as EDT as well. In 2006 EDT did not go into effect until April 2nd, so it should see that date as Eastern Standard Time (EDT). This is an issue for us, as we do a lot of historical reporting. Has anyone else running 6.3 Patch 20 (or 7.1 Patch 1) noticed any problems with Daylight Saving time calculations for 2006 or prior years?
