Once every hundred years, our time and calendar line up to make the amazing time of 12:34:56 7/8/9. And since this post went up exactly at that time, you totally missed it.
Nice work, jackass! You were probably doing something totally boring and didn't look at your watch right as that second passed. The rest of us, who were paying close attention, sort of half smiled and though "oh, neat" to ourselves before going back to work.
If you're desperate for that same feeling, there's always 04:05:06 07/08/09 later this afternoon.
