Скачать или смотреть How a Computer Stores Time: Binary Unix Epoch Clock

A clock that displays time as the number of seconds that have elapsed since midnight UTC on January 1, 1970. This is how computers "tell" the time.

Midnight UTC, January 1, 1970, is the start of the Unix Epoch. It is the date computer scientists chose when they had to agree on a universal date to start counting time from.

The number of seconds since the epoch is represented as a 32-bit binary integer. Binary is a number system with two values , generally represented as 1 and 0. (Normal numbers, written with 0-9, use what is called the decimal system.) In this case, 1 and 0 are represented by the LED either being on or off.

The clock contains the following components:
1 - Arduino Uno
2 - TLC5490NT
32 - 3mm red LEDs
1 - DS1307-based RTC (Tiny RTC)
