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.<Ncorresponds to Olsen tzdata2006<Lwhere
<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.
