DateTimeZone::getTransitions() returns insufficient data

[mvorisek]

Description

The following code:

var_dump(
    (new \DateTime('2203-10-05 15:05:37.180157', new \DateTimeZone('America/Los_Angeles')))
    ->getTimestamp()
);

produces different result on PHP 8.1 vs PHP 7.4/8.0

it is from our failing unit test, what result is correct and any plain to bugfix in either PHP 8.1 or the PHP 8.0 and lower?

PHP Version

PHP 8.1.0

Operating System

linux

It seems the bug starts with 2100-03-14 03:00:00 while 2100-03-14 02:59:59 works fine.

On PHP 8.1 2100-03-14 03:00:00 under the America/Los_Angeles time zone has the same timestamp as2100-03-14 02:00:00.

It seems that transitions are not tracked far in the future, and that neither version is totally correct; apparently, prior to PHP 8.1.0 DST was always assumed, while as of PHP 8.1.0 standard time is assumed (what would make more sense).

@derickr, can you please clarify?

All transitions in the future except for the next seem to be gone. (might be by design, not sure)

[derickr]

I'm going to have to check this, as the new code should definitely handle this correctly.

Can some one tell when this issue will be fixed? We added now hacks in our code base for getting now the correct timestamp.
