I dont think your TIMEZONE is rigth for SVR3.2  and Paris daylight time.

Here is what I use for 1991 Paris time:

TZ="MET-1DST-2;90/02,272/03"
 
Unfortunatley we have a case of pretty wierd thinking here:
Negative TIMEZONE values gives times east of Greenwich ( London ) while
positive TIMEZONE values gives times west of Greenwich.  And not the other
way around which would be more logical, at least to me.

So since Paris daylight time is 2 hours ahead of GMT, it needs to be defined 
with DST-2 otherwise UNIX dont know which time to shift to. There was no
value assosiated with DST in your example above.
