-/// A type that can measure and format the current time.
-///
-/// This trait is used by `Format` to include a timestamp with each `Event` when it is logged.
-///
-/// Notable default implementations of this trait are `SystemTime` and `()`. The former prints the
-/// current time as reported by `std::time::SystemTime`, and the latter does not print the current
-/// time at all. `FormatTime` is also automatically implemented for any function pointer with the
-/// appropriate signature.
-///
-/// The full list of provided implementations can be found in [`time`].
-///
-/// [`time`]: ./index.html

- /// Measure and write out the current time.
- ///
- /// When `format_time` is called, implementors should get the current time using their desired
- /// mechanism, and write it out to the given `fmt::Write`. Implementors must insert a trailing
- /// space themselves if they wish to separate the time from subsequent log message text.

-/// Returns a new `SystemTime` timestamp provider.

-/// tracing_subscriber::fmt::time::SystemTime::default()

-/// configured.
