Yes, it is the government mandated silliness called “DayLight Savings”, It was originally a joke that Benjamin Franklin pulled on congress. Later, they bought it hook, line and sinker and foisted it off on us. Therefore, we all have to change our clocks twice a year to appease their silliness. I notice that the animals don’t abide by this idiocy. They just do their thing at the same “time” every day!
