status: Extract TruncatedTimestamp from fs::Metadata without SystemTime
On Unix, the Rust standard library exposes `mtime` and `mtime_nsec` methods
for `std::fs::Metada` whih is exactly what we need to construct a
`TruncatedTimestamp`. This skips the computation in the conversion through
`SystemTime` and `Result<Duration, Duration>`.
