Set your alarms.
Get up early.
Celebrate a once in a century moment.
Yes, tomorrow at six minutes past five or, to be more exact, at seven seconds past six minutes past five it will be:
05:06:07 on 8th September.
Or, in other words:
05:06:07 08/09/10[Sorry Americans, your day happened a month ago on 9th August]
This sequence of numbers won't happen again until 2110 … wowser!
Oh yes, of course, if you're a bit late in the day, then just think the same at 17:06 but use a 12-hour clock.
