Interesting...

If you wish, try this:

In NET tab, find this:

Code:

//RTC.adjust(DateTime(year(), month(), day(), hour(), minute(), second()));        // Adjust RTC with local time        
RTC.adjust(local);

and replace with this:

Code:

RTC.adjust(DateTime(year(), month(), day(), hour(), minute(), second()));        // Adjust RTC with local time        
//RTC.adjust(local);

Theoretically it should give the same result, but, strangely not always.
