Microsoft has released a hotfix designed to introduce three new changes in Windows Daylight Saving Time support for Windows 7 Service Pack 1 (SP1).
At the same time,
KB 2543367 is designed not only for Windows 7 SP1, but also for all supported versions of Windows.
According to the Redmond company, customers running Windows and living in the following countries: Chile, Egypt, and Morocco will be interested in deploying the hotfix.
The Windows Daylight Saving Time support modifications introduced are designed to reflect changes in the DST policies in each country.
The software giant offered details of the changes that the hotfix introduces:
“The government of Egypt has decided to cancel Daylight Saving Time. This hotfix updates Windows support for (UTC +2:00) Cairo so it will no longer have DST support.
The government of Chile has extended the 2011 Daylight Saving Time so it ends May 7th. This hotfix updates Windows DST support for (UTC -4:00) Santiago so that DST ends May 7, 2011 at 23:59:59.999 and the clock reverts to 23:00:00.000.
The government of Morocco has changed the 2011 Daylight Saving Time schedule to end July 30th at midnight. This hotfix updates Windows DST support for (UTC) Casablanca so 2011 DST ends July 30, 2011 at 23:59:59.999 and the clock reverts to 23:00:00.000.”
The hotfix, which can be
downloaded from Microsoft support is designed to introduce only the changes enumerated above, and nothing else.
Fact is that customers in other markets than Chile, Egypt, or Morocco can go ahead and ignore this particular DST hotfix entirely, since it’s completely useless to them.
KB 2543367 also contains extensive details about the Registry Keys changes operated by the deployment of the hotfix, and IT admins might want to have a look and see exactly what the fix modifies.
