How to implement the relay switching times per day?
The bottom line is this, alternately running pumps should switch once a day(one off of the other involved), but the catch is that the Board is not connected neither to PC nor to the Internet to know the time, I am so confused
Well, if you really want to learn to do, then buy the sensor real-time (e.g. DS1307), relays, and code accordingly write to MK took time from the sensor and every 24 hours switched relay. But in General it will be the farm, better to do without the MC, as described above.

And what prevents a fee to put your own watch? And if the task Board is only switching the pumps, and the microcontroller is not required, only the clock and bistable relays.

For this task, even the microcontroller is not needed.
To buy any ehlektromagazin mechanical timer sockets and changeover contactor (really dial them just for a day, switching the 12h of pumps even better)
