+Subject: [PATCH] Handle various time_t sizes in printf and scanf
+
+The members of the timeval struct are both signed (defined by POSIX)
+and typically both 64 bits on a system where time_t is 64 bits.  This
+is possible also on 32 bit systems where time_t is larger to handle
+the 2038 problem.
+
+It's practically impossible to find a type and printf format that
+works even on all glibc systems.  Play it safe and always use printf
+with intmax_t and explict int64_t variables for scanf.
