As others suggested, perhaps it is early for a pattern to be asserted.
What happens, next year, if nothing is announced, at what point should we
pull out the pattern rule. At the moment we get about a months notice for
change from Fiji, but next year would we wait until the week before before
pulling the pattern. Are we making this potentially worse for end users
of the DB.
I work in the airline industry, we issue tickets up to 350 days in advance
of travel. When a country makes late DST changes it causes some
inconvenience for business and customers alike. I now also wonder if the
presumption of a pattern might cause conflicts with other sources. IATA /
Microsoft etc.
With regard to the comment about the release will be before October 21, of
course as we are selling tickets so far in advance, for us, anytime after
October last year is too late. Also, only when the Olson DB update is
released, do vendors get to start work on their own patches... For Java
(no flames please) for instance, the JVM vendor often does not release
their own patch until 4 to 6 weeks after the Olson change (both Oracle and
IBM).
Fortunately, being Java (still no flames please), we are able to patch the
JVM without waiting for the vendor by adding a single jar file to the
bootclasspath we can effect the required timezone changes for the JVM and
JodaTime and can do this within hours of an announced change if need be.
