My camera can only record in 60fps, while the LED is blinking at 256Hz, so the LED blinking is not recorded completely correct, but this 12 RGB LED clock works as coded. 3 buttons work perfectly. Most of the time, the MCU is in sleep mode.

5 display modes - Consuming 36uA in average (about 300 days on a 300mA CR2032 battery cell)
1 set time mode - to change hour and minute
1 LED Off mode - Consuming 800nA while the clock is running accurately (about 300/0.0008/24=15625/365=42 years!!!)
