Also, when are we going to do 10hrs/day, 100 min/hr and 100s/min?

This is how you collectively give the entire scientific community a simultaneous aneurysm. The amount of work needed to convert measurements based on our current seconds/minutes/hours to your “metric” seconds/minutes/hours would be astronomical.

Also, pretty much everyone already agrees on the current system of time, so why change it? It would just create another metric/imperial or F/C divide and cause conversion mistakes.
