fix timer test to be less reliant on float precision (#3789)

Browse source 
# Objective

- Test is failing on nightly after the merge of https://github.com/rust-lang/rust/pull/90247
- It was relying on the precision of the duration of `1.0 / 3.0`

## Solution

- Fix the test to be less reliant on float precision to have the same result
