It's about time

Monday morning comes on Tuesday this week. That's logical Monday; actual Monday was President's Day in the United States, an official holiday on which companies honor Presidents Abraham Lincoln and George Washington by freeing all the (wage) slaves for a day and by being temporarily unable to tell a lie (the marketing department gets the day off, too).

For Java developers in the United States, a possibly more significant date is March 11. That's when Daylight Savings Time starts. The significance of this is that the date is inconsistent with rules prior to 2005, and since the JRE stores such rules, apps running on older JREs are likely to report incorrect times starting on March 11.

But the changes are more complicated than that. Apple has had to issue several updates to address DST formula and time zone changes throughout the world.
