    PHP version verses timezonedb version verses Olsen timezone database version

    Q1: I am looking to find/build a table of PHP version verses timezonedb
    version shipped with it.
    For example, I think that 5.2.0 updated the timezonedb to the 2006.14
    version.
    Is there a table of PHP version verses timezonedb version.

    Q2: I am also looking to find a table of timezonedb version verses
    Olsen timezone database used to construct it.
    For example, I think that the 2006.16 version corresponds to the Olsen
    tzdata2006p.

    We are very keen to obtain these tables, so that we can determine the
    extent of our exposure the 2007 US DST change, resulting from the US
    Energy act.
    As US DST will happen soon, we have an interest in understanding sooner
    rather than later...
    We have a variety of PHP versions in use, but can only assess which are
    impacted if we can ultimately map each to a particular Olsen version,
    as we know (or rather, IBM helpfully collated) what changes went into
    each.

      Not sure how to get this information... Maybe there's a test to see if
      DST is being properly handled...? FWIW, the release dates for
      timezonedb are here: http://pecl.php.net/package/timezonedb.

          Thanks, but had seen that link already.

          Another alternative may be to difference the .xml files included in the
          packages, and try to correlate that to changes in Olsen tzdata - not
          easy, or necessarily foolproof...

              http://pecl.php.net/bugs/bug.php?id=9109 strongly suggests that
              timezonedb version 2006.<Ncorrespo nds to Olsen tzdata2006<Lwhe re
              <Lis the <N>th letter of the alphabet.
              Hence 2006.14 corresponds to tzdata2006n and 2006.16 corresponds to
              tzdata2006p.

              So now I'm left with the question as to which levels of PHP include
              which levels of timezonedb.
