The  Display DST  (Daylight  Savings  Time)  Date command  displays  or
lists  the start  and end date/times  for daylight  savings time  for a
time  zone  in a  specific  year.   The  system support  for  Time Zone
Descriptions does not include actual dates of change.

A typical command would be:

             DSPDSTDAT

The command defaults to use  the time zone of the system  value QTIMZON
and the current year.
