There are some regions in the world where during summers and springs, the days are longer than during the winters. Usually, when it’s summer or spring, the daylight saving time changes by one hour so it changes the windows time on the system according to the DST (Daylight Saving Time).
But recently many windows users reported that the system time on their windows system does not change properly and they feel it is not showing the accurate time. Some software might not run properly if the system time is not accurate in some cases and the option called Adjust for daylight saving time automatically option is greyed in the Windows system which is actually creating a problem for them.
