The closing parentheses around the read syscall is misplaced, causing
single byte reads from the iterator instead of buf sized reads. While

Newer architectures (like riscv32) do not implement sys_gettimeofday().
In those cases fall back to sys_clock_gettime().
While that does not support the timezone argument of sys_gettimeofday(),
specifying this argument invokes undefined behaviour, so it's safe to ignore.
