Subject: Explain field

Could you please explain to me what seem to be a contradiction in the
documentation (File: "tzCode2009e\Zic.8.txt")

For the Rule part, you say that the field "FROM" ... "Gives the first
year in which the rule applies". Then from the example you say that ...
"After 1894-06-01 at 00:00 Swiss daylight saving rules (defined with
lines beginning with "Rule Swiss") apply"... but the "Rule Swiss"
begin in 1940. There is a laps in time here that I don't understand.

Maybe should you also update this document to reflect the change in file
for Swiss.
