commit 35187508cfaf3fd21ed68159f4635ee2d376aea4
Author: Taylor R Campbell <campbell+torsocks at mumble.net>
Date:   Fri Jun 19 04:23:36 2015 +0000

    Use seconds since epoch, not local time, for log timestamps.
    
    Local time may require opening files to load the time zone database, which
    leads to a potential deadlock-against-self when intercepting a close() in the
    middle of tsocks_once initialization for close().
    
    The same issue applies even if we use UTC, via gmtime.
