That's as may be, but this discussion revolves around:

 "The M format is sufficient to describe many common daylight-savings
  transition laws. But note that none of these variants can deal with
  daylight-savings law changes, so in practice the historical data
  stored for named time zones (in the IANA time zone database) is
  necessary to interpret past time stamps correctly."

 (from some random POSIX Time Zone Specifications)
