A singularity

Rico says his friend Doug sends this along:

At five minutes and six seconds after four o'clock on the morning of the 8th of July of this year, the time and date will be 04:05:06 07/08/09. This will never happen again.

It will, of course, happen a year, a month, a day, an hour, a minute, and a second later, ad infinitum, at least up until 09:10:11 on 12/13/14, when it will finally run out of digits...
