PHP 8.4 adds a new interface method DatetimeImmutable::createFromTimestamp().

The signature mismatch issue on PHP 8.4 is easily fixable but as seen from the failed tests the result of DateTimeImmutable::createFromTimestamp() is different than our implementation.

The change in behavior will need to be documented in the release notes. If $timezone is not explicitly passed then the instance has timezone set to +00:00 unlike earlier where the currently set default timezone was used.

public static function createFromTimestamp(float|int $timestamp, DateTimeZone|string|null $timezone = null): static
{
return static::now($timezone)->setTimestamp($timestamp);
$instance = PHP_VERSION_ID >= 80400 ? parent::createFromTimestamp($timestamp) : new static('@' . $timestamp);

Now that we accept float, do we need to do any special rounding/etc to mimic the 8.4 behavior when converting to a @timestamp ?

I hope not. I assume they expect the timestamp to still be an integer in float format.

No, the fractional part of floats is used as microseconds https://3v4l.org/OT84B#v8.1.0
We don't have to do any additional processing.

ah, ok. Wasn't sure if the @ format would throw an error, but I think that's ok if it does.

I started a draft release for 3.1 with the behavior change we've inherited from PHP.
