Why all of the electric clocks including radio clock in my house is running fast? about 15 - 30 second a day. I am living in a country with 220-240 V. please anybody can advice how to solve this problem ? many thanks in advance.

Some parts of the world have 50 hertz electricity while others have 60 hertz. Utilities in the US watch the frequency very carefully to make sure that the average stays at 60 hertz.
A 60 hertz designed clock will run 1/6 slow on a 50 hertz power supply, but this is much bigger than your discrepancy. So, I suspect that either the local utility is not managing the frequency well or that the "standard" you are comparing to is running slightly fast.

I presume you have mains electrical energy. The voltage is irrelevant , it relies upon on the frequency of the availability which would be the two 50 or 60 hertz. this suggests 50 or 60 complete pulses of electric energy each and every 2d that's 3000 or 3600 pulses according to minute and this determines the value in revs according to minute of the motor which drives your clock. except you're in a small remoted u . s . a . city or a marginally backward u . s . a . the means authority has to verify the final frequency over a fifteen minute era is strictly the known on your u . s . a .. touch your interior of sight electrical energy authority.

Turn them off.
They will be correct at least twice a day.
