Dear List,
I have a question about the following data lines

# Rule  NAME    FROM    TO      TYPE    IN      ON      AT      SAVE    
LETTER/S
Rule RussiaAsia 1992    only    -       Mar     lastSat 23:00   1:00    S
Rule RussiaAsia 1992    only    -       Sep     lastSat 23:00   0       
-     # i.e. Sep 26
Rule RussiaAsia 1993    max     -       Mar     lastSun  2:00s  1:00    S


# Zone  NAME            GMTOFF  RULES   FORMAT  [UNTIL]
Zone    Asia/Baku       3:00    1:00    BAKST   1991 Aug 30 # independence
                        3:00 RussiaAsia AZ%sT   1992 Sep lastSun 
2:00s    # i.e. Sep 27
                        4:00    -       AZT     1996 # Azerbaijan time

Now if I try to interprete these lines I get:
from 1992 Mar to 1992 Sep 26 23:00 (local): GMTOFF= 3:00 and SAVE= 1:00 
i.e. LOCALOFF= +4:00
==> 1992 Sep 26 23:00 (local) == 1992 Sep 26 19:00 zulu
from 1992 Sep 26 19:00 zulu to 1992 Sep 26 23:00 zulu: GMTOFF= LOCALOFF= 
+3:00
from 1992 Sep 26 23:00 zulu to 1996: GMTOFF= LOCALOFF= +4:00

This would mean a local offset change ocurred for only four hours.

Is this correct?

Best Regards,
Klaus Schmid
