Flaky test for IntlDateFormatter [dateformat_format_relative.phpt]

[SakiTakamachi]

Description

The test fails at certain times.
https://github.com/php/php-src/actions/runs/6767338868/job/18389812623

The following code:

<?php
$formatter = new IntlDateFormatter(
    "en_US",
    IntlDateFormatter::RELATIVE_FULL,
    IntlDateFormatter::NONE,
    "America/Los_Angeles",
    IntlDateFormatter::GREGORIAN,
);

echo $formatter->format(new DateTimeImmutable("yesterday"));

result:

Saturday, November 4, 2023 // now is 2023-11-06 11:08:00 UTC

This is due to time zone mismatch. I thought it would be enough to just specify the time zone in DateTimeImmutable, but there are places in the test where it is purposely set to UTC, so I don't know what the purpose of the test is.

php-src/ext/intl/tests/dateformat_format_relative.phpt

Line 53 in 4022e28

return new DateTimeImmutable("2020-01-20 20:20:20", new DateTimeZone("UTC"));

Is it okay to just set the time zones?
