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 (that is, the offset).
Example
