PercenTime the New Approach to Timekeeping

Introducing a new approach to timekeeping: a method that transcends traditional hours, minutes, and seconds. By representing time as a percentage of the day, this system simplifies time perception to its essence.

If you check my profile you can see I like clocks and my motto: Think outside the box.

I think it's time to change the time. There is an article about analog clocks, the new generation prefers the digital world.

There are other articles about the confusion of the 12 or 24 hours system.

My simple clock shows the time as a percentage of the day. No hours, no minutes, no seconds.

The circuit includes an ESP12 and an OLED display. ESP12 receives the time from the NTP server, calculates the time in seconds, and divides it by 86400

The last digit changes every 9 seconds, which is a better resolution than the 1 minute resolution of a normal clock
