Description OSIDB Bzimport 2026-01-04 21:06:46 UTC 
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`.
