COMMAND USAGE
◆ 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.
◆ This command sets the summer-time zone relative to the currently
configured time zone. To specify a time corresponding to your local
time when summer time is in effect, you must indicate the number of
minutes your summer-time zone deviates from your regular time zone.
