Real time clock is a waste of time to diagnose on a old phone. Better yet to get another 2nd hand iPhone 4 rather than try to fix the problem as it would be a lot cheaper and less time spent.
 
You could try restoring the phone via iTunes but you would need to do a backup first. I doubt it'll help though.
