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!
