Subject: [PATCH 1/2] nfs-utils: print time in 64-bit
Date:   Fri,  3 Apr 2020 22:24:52 -0700
Message-Id: <20200404052453.2631191-1-rosenp@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-nfs-owner@vger.kernel.org
Precedence: bulk

musl 1.2.0 defines time_t as 64-bit, even under 32-bit OSes.

Fixes -Wformat errors.
