```
session.Session.last_attached(self) -> Option<SystemTime>
```

Return when a client last attached.

This is `None` for a session that has never been attached, which is the
ordinary state for one started with `new-session -d`. tmux keeps whole
seconds. `SessionFields::session_last_attached` filters and reads the
same field as the `i64` of Unix seconds tmux reports, because the query
grammar compares integers.
