The extra timeout tolerance was too short for my machine, which would often exceed by a few milliseconds. I made a few tweaks to clarify when this happens and increase the tolerance from 10ms to 25ms. I can push them to this branch soon, if that's okay with you.

2    use dicom_ul::ClientAssociationOptions;
3    use rstest::rstest;
4    use std::time::Instant;
   6 const TIMEOUT_TOLERANCE: u64 = 25;
   7 
   8 #[rstest]
   9 #[case(100)]
   10 #[case(500)]

17        let now = Instant::now();
18        let _res = scu_init.establish_with("RANDOM@167.167.167.167:11111");
19        let elapsed = now.elapsed();
20        assert!(elapsed.as_millis() < (timeout + 10).into());
   22     assert!(
   23         elapsed.as_millis() < (timeout + TIMEOUT_TOLERANCE).into(),
   24         "Elapsed time {}ms exceeded the timeout {}", elapsed.as_millis(), timeout
   25     );
   26 }
   27 
   28 #[cfg(feature = "async")]

ul/tests/association.rs --- 3/3 --- Rust
38            .await;
39        assert!(res.is_err());
40        let elapsed = now.elapsed();
41        println!("Elapsed time: {:?}", elapsed);
42        assert!(elapsed.as_millis() < (timeout + 10).into());
   47     assert!(
   48         elapsed.as_millis() < (timeout + TIMEOUT_TOLERANCE).into(),
   49         "Elapsed time {}ms exceeded the timeout {}ms", elapsed.as_millis(), timeout
   50     );
   51 }

Should be OK now. 👍 Thanks!
