                     15: settz is one of the  suite of COHERENT functions that control and
                     16: display  the system's  time.  It  searches for  the environmental
                     17: parameter  TIMEZONE, which  gives information  on the  local time
                     18: zone.  For more information on TIMEZONE, see its Lexicon entry.
                     19: 
                     20: If  TIMEZONE is  set,  settz initializes  the external  variables
                     21: timezone and tzname.   timezone contains the number of seconds to
                     22: be subtracted from  GMT to obtain local standard time.  tzname[0]
                     23: and tzname[1]  are character arrays that  hold, respectively, the
                     24: names  of the  local standard  time zone  and the  local daylight
                     25: saving time  zone.  If TIMEZONE is not  set, timezone defaults to
                     26: 0, tzname[0] to GGMMTT, and tzname[1] to the empty string.
