IBM has created a new site (sub-site?) to document problems that affect lots of products.
The site is IBM Alerts.
The first pervasive problem it tackles is Changes to Daylight Saving Time in 2007, which I discussed a month ago in Daylight Savings Time and Java. For example, select Software, then W, then WebSphere Application Server Action required, and you get the #1219396 flash alert document I pointed out back then.
