I would consider using just seconds. As time units are largely based off fractions like 1/24 & 1/60, you will definitely get repeating decimals when doing...
You could multiply the hrs/min/sec out of the equation, effectively expressing your time as a decimal fraction of seconds (the multiplier is 60*60*24 = 86400)....

I think strictly speaking Dr. Stockton is wrong. Regarding the time designator there is not any difference between the first (1988), second (2000) and third...

Why can't everyone see how illogical it is to insert the year after the day and before the time? Why is there so much resistance to the use of the logical...

The only thing I never liked about this was the time of day: Its main unit is a decimal multiple, but what kind of multiple is the question. Not a straight...
