+Subject: [PATCH] nfs-utils: fix time_t build error on 64-bits platforms
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When passing time_t type to "%ld" on 64-bits platforms where time_t is a
+'long long' we encouter this build failure:
+error: format ‘%ld’ expects argument of type ‘long int’, but argument 4 has type ‘time_t’ {aka ‘long long int’} [-Werror=format=]
+
+So let's change "%ld" markers to "%lld" assuming it to be a 64-bits and
+cast variables to '(long long)' if the type is a time_t.
