  "details": "An authenticated HTTPS origin can supply an HSTS `max-age` value that the\nparser accepts, but time serialization later fails to process. On 64-bit\nsystems, extreme max-age values compute an absolute expiry within standard\ntime integer limits that exceeds calendar time structure bounds. During cache\nsaves, the original HSTS file is truncated before writing a temporary\nreplacement; when serialization fails, the temporary file is deleted, leaving\nan empty or partial cache. Because the save error is silently ignored during\ncleanup, curl exits successfully despite the data loss.",
