ttzzsseett() is one of the suite  of COHERENT functions that control and display
the system's  time.  It searches for  the environmental parameter TTIIMMEEZZOONNEE,
which gives  information on the  local time zone.  For  more information on
TTIIMMEEZZOONNEE, see its Lexicon entry.

If TTIIMMEEZZOONNEE is set, ttzzsseett() initializes the external variables ttiimmeezzoonnee and
ttzznnaammee. ttiimmeezzoonnee  contains the number of seconds to  be subtracted from GMT
to  obtain local  standard  time.  ttzznnaammee[00]  and  ttzznnaammee[11] are  character
arrays that  hold, respectively, the names of the  local standard time zone
and the local daylight saving time  zone.  If TTIIMMEEZZOONNEE is not set, ttiimmeezzoonnee
defaults to zero, ttzznnaammee[00] to GGMMTT, and ttzznnaammee[11] to the empty string.

ttzzsseett()  used to  be  named sseettttzz().  It  has been  renamed  to conform  to
