/// Since we already replace the `std::time::Instant` type with

///
/// 1. Consistency. With this approach, you don't have to remember
/// which type uses `get` and which uses `now`.
/// 2. Enforcement. This approach makes it possible to use Clippy
/// to disallow `std::time::Instant::now()` unconditionally,
/// to make sure that you don't forget to use
/// the appropriate `web_time_compat::Instant` type instead.
