Signs of the times

John Walkenbach, J-Walk to his readers, posts some of the most amusing stuff. Today, he points out two date-and-time events that will happen only once... ever (except maybe in some parallel dimension like the one where Spock has a beard):

• This will happen only once: On Wednesday, at two minutes and three seconds after one in the morning, the time and date will be 01:02:03 04/05/06.
• This will happen only twice: On Tuesday, June 6th your clock may display something like this: 06:06 06/06/06.
