Subject: warc: test future date conversion
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=535360bfebfdb0ee8bb5030d88eaafa0e11edd20;p=thirdparty%2Flibarchive.git

warc: test future date conversion

Add a WARC date after 2038 to cover the fallback time conversion.
On 64-bit time_t, it must parse as the expected Unix timestamp.
