Symfony version(s) affected

6.0.7

Description

After updating RateLimiter component to 6.0.7 tests starts to showing "Implicit conversion from float x.xxx to int loses precision" deprecation message. I'm using sliding window policy.

How to reproduce

Example Symfony config

# config/packages/framework.yaml
framework:
    rate_limiter:
        foo_action:
            policy: sliding_window
            limit: 15
            interval: '60 minutes'
            lock_factory: null

then try to use RateLimiter:

final class FooAction
{
    public function __construct(
        private readonly RateLimiterFactory $fooActionLimiter,
    ) {
    }

    public function __invoke()
    {
        $limiter = $this->fooActionLimiter
            ->create('test')
        ;
        $limit = $limiter->consume();

        if (false === $limit->isAccepted()) {
            throw new \RuntimeException('Too many actions.');
        }
    }

Possible Solution

In \Symfony\Component\RateLimiter\Policy\SlidingWindow::getExpirationTime method, $this->windowEndAt and microtime return value are floats, converting type should help: return (int) $this->windowEndAt + $this->intervalInSeconds - (int) microtime(true); or change return type to float: public function getExpirationTime(): float.

Additional Context

Earlier patch version (6.0.x) works without deprecation.
