What is it?

Cannonian Time is metric time. There are 100 hours in a day!

Why is it better?

The current 24/60/60 system was 'invented' roughly 3000 years ago by the Ancient Egyptians and Babylonians and improved by the Ancient Greeks. It is based upon a base-12 system, which is the counting system they used at the time. We've obviously progressed quite a bit since then! We now use a base-10 system, and practically every measurable entity can be measured metrically. Except time. Until now.

How does it work?

Cannonian Time has 100 hours to a day, 10 minutes to an hour, and 100 centiminutes to a minute. Days, weeks, months and year all remain the same.
