From ac66a2546084b6e59d0ea17a1386d6b0d512afea Mon Sep 17 00:00:00 2001
From: dholland <dholland@pkgsrc.org>
Date: Mon, 18 Jun 2012 04:45:47 +0000
Subject: Fix time handling; avoids need to use -lcompat and should fix the
 Linux build. While here, tidy a couple bits of pkglint. PKGREVISION -> 3.

Set LICENSE to generic-nonlicense as that appears to describe the situation.

+- use gettimeofday() rather than ftime(), which is very obsolete
+- don't truncate time_t (or worse, time_t * 1000) to int
+
+Note that because all times used elsewhere are relative, we can get
+away with subtracting off the start time like this. We could also
+probably get away with truncating to int, except that (a) it's untidy,
+(b) likely to attract attention from program checkers, and (c) can
+result in formally undefined behavior if we happen to be running
+across one of the moments where the milliseconds value passes through
+signed overflow.
