Subject: [PATCH 31/34] os-util: Handle negative time_t values properly
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: 8bit

musl's time framework happily accepts dates before 1970, which can
result in negative time_t values being returned.  These should still be
considered as invalid dates for OS support.
