commit 03f887ca1213744e2da3ec50f46d9fe3bc269510
Author: Viktor Dukhovni <openssl-users at dukhovni.org>
Date:   Tue Jan 12 21:13:34 2016 -0500

    Maximize time_t when intmax_t is available
    
    Well, I'm not actually changing time_t, just changing how time_t
    valued opt values are converted from string to time_t.
