clang still complaining:

syscall_timing.c:766:24: warning: conversion specifies type 'int' but the argument has type 'uintmax_t' (aka 'unsigned long') [-Wformat]
                        printf("%ju.%09ju\t%d\t", (uintmax_t)ts_end.tv_sec,
                                           ~^
                                           %lu
1 warning generated.

cheers.
