COMMAND USAGE
â—† In some countries or regions, clocks are adjusted through the summer
months so that afternoons have more daylight and mornings have less.
This is known as Summer Time, or Daylight Savings Time (DST).
Typically, clocks are adjusted forward one hour at the start of spring
and then adjusted backward in autumn.
