+From 9048939b76b3bd10783adb79ed0aaf6cd13895cc Mon Sep 17 00:00:00 2001
+From: Christopher Larson <chris_larson@mentor.com>
+Date: Tue, 13 Dec 2016 20:39:51 -0700
+Subject: [PATCH 1/2] gnome-desktop-thumbnail: don't convert time_t to long
+
+Explicitly use strftime+strptime rather than snprintf+atol. This fixes the
+build for X32, where long's size doesn't match that of time_t.
+
+Upstream-Status: Pending
+Signed-off-by: Christopher Larson <chris_larson@mentor.com>
+
+
+Modify patch described above to eliminate replacement of
+
+g_snprintf (mtime_str, 21, "%" G_GINT64_FORMAT, (gint64) mtime)
+
+which is not necessary.  Retain replacement of atol().
