We use the Olson timezone data, from ftp://elsie.nci.nih.gov/pub/

Here's the relevant bits for Santiago. see zic(8) for the format.

Rule    Chile   1999    max     -       Oct     Sun>=9  4:00u   1:00    S
Rule    Chile   2000    max     -       Mar     Sun>=9  3:00u   0       -
# IATA SSIM anomalies: (1990-09) says 1990-09-16; (1992-02) says
1992-03-14;
# (1996-09) says 1998-03-08.  Ignore these.
# Zone  NAME            GMTOFF  RULES   FORMAT  [UNTIL]
Zone America/Santiago   -4:42:40 -      LMT     1890
                        -4:42:40 -      SMT     1910        # Santiago Mean Time
                        -5:00   Chile   CL%sT   1932 Sep    # Chile Time
                        -4:00   Chile   CL%sT


If it was 'Sun>=8' we could use BYDAY=2SU, but I don't know what we
can do with 'Sun>=9'.
