[tz] Zone America/Argentina/San_Luis possible rule inconsistency

Hi,    with respect to 2012c south america. San Luis appears to have a zone/rule inconsistency. The latest zone indicates using rule SanLuis, but the rule is used only until 2009. For dates past 2009 is there consistency?  # San Luis (SL) Rule    SanLuis 2008    2009    -       Mar     Sun>=8  0:00    0       -Rule    SanLuis 2007    2009    -       Oct     Sun>=8  0:00    1:00    S Zone America/Argentina/San_Luis -4:25:24 - LMT  1894 Oct 31                        .                        .                        .                        -3:00   Arg     AR%sT   2008 Jan 21                        -4:00   SanLuis WAR%sT Thanks, Larry.
