I commented last week that the forthcoming changes to Daylight Savings Time in the US is likely to cause big pain for lots of people.
It turns out that one of the biggest problems around (the updating of the multiple JVMs that everybody has) isn't as bad as I feared.
This article on IBM developerWorks introduces a new tool that can search a machine for IBM JVMs and offer to update them.
(Note: the version currently published is a version for early adopters. The best advice is probably to apply patches to existing applications and supported JVMs and then run this tool later on in order to catch any JVMs that were misssed)
