Zero time DEC 10 1998
An interesting thought, courtesy of PeterMe: Why does time start at 12? Shouldn't it start at 0? 0 o'clock, 1 o'clock, etc. instead of 12 o'clock, 1 o'clock, etc.
It's a similar problem to the first year's start date...it started at year 1 instead of year 0. Except that years don't loop back on themselves as hours do, so instead of 1=0 when dealing with years, 12=0 when dealing with time. Weird.
