Patch to fix the issue

On Linux it is valid to call {get,set}timeofday() with a null timeval
pointer and non-null timezone pointer.  This will get or set the
kernel's local time offset, which is used for converting timestamps on
brain-dead filesystems like VFAT.  settimeofday(NULL, tz) is also used
to fix the system time during the boot process if the RTC is set to
local time for compatibility with a similarly brain-dead operating
system.

Patch to fix the problem is attached.

These are invalid calls.  These calls should then use the syscalls directly and
not cause everyone else to suffer from not being warned about invalid uses.
