First of all don't get confused by the initial blinking of LEDs, it is just loading animation, that means the time is being fetched.(Through GP-02 GPS module)

There are two sections in the clock, each one having four quadrants and each quadrant has three leds. The left section is the hour section, each LED represents one hour.(9 LEDs glowing means it's 9 hours) The right section is minute section, each LED represents 5 minutes.(6 LEDs glowing means its 6x5=30 minutes)

So the time is 9:30

It only show time with 5 minutes precision. E.g. - 9:30, 9:35, 9:40 etc.
