I've always loved the numerical coincidence that, to a fairly crude approximation (a bit better than two decimal places), π billion seconds is a century.
That's fascinating! Never thought about that before. π is an amazing number.
The odometer has wrapped!
I just thought it was inspiring that we only get to live 3-4 billion seconds at most, seconds count.
Celebrating it also certainly beats celebrating birthdays :)
Also, if you'd like, I can modify it to track the 2nd and 3rd billion(th) seconds. I know I'll be needing it soon ;)
Personally, I wouldn't vote for a change. Less counting of rollovers is fine with me these days.
