Description
The function gix_date::parse::TimeBuf::as_str can create an illegal string containing non-utf8 characters. This violates the safety invariant of TimeBuf and can lead to undefined behavior when consuming the string.
The bug can be prevented by adding str::from_utf8 to the function TimeBuf::write.
