And if you have BSD /etc/zoneinfo (and /etc/tzic), compile something like this:

# Rule  NAME    FROM    TO      TYPE    IN      ON      AT      SAVE LETTER/S
Rule    M-GMT   1986    max     -       Mar     lastSun 2:00s   1:00 "+0200"
Rule    M-GMT   1986    max     -       Sep     lastSun 2:00s   0    "+0100"
# Zone  NAME            GMTOFF  RULES/SAVE      FORMAT   [UNTIL]
Zone    MET             1:00    M-GMT           %s

Your mileage may vary, esp. on when your DST changes.
"lastSun" obviously is the last Sunday of that month. You can do stuff like
"Sun>23" or "Sun>=1" or "1" (for a specific day). For the US and Canada, the
rules are:
Rule    US      1967    max     -       Oct     lastSun 2:00    0       S
Rule    US      1967    1973    -       Apr     lastSun 2:00    1:00    D
Rule    US      1974    only    -       Jan     6       2:00    1:00    D
Rule    US      1975    only    -       Feb     23      2:00    1:00    D
Rule    US      1976    1986    -       Apr     lastSun 2:00    1:00    D
Rule    US      1987    max     -       Apr     Sun>=1  2:00    1:00    D
Rule    Canada  1969    max     -       Oct     lastSun 2:00    0       S
Rule    Canada  1969    1986    -       Apr     lastSun 2:00    1:00    D
Rule    Canada  1987    max     -       Apr     Sun>=1  2:00    1:00    D
Replace the "S" and "D" in the last column with "-0x00", depending on where
you live. EST is -0500, PST -0800, PDT -0700.
