This advice looks correct. If you use the source Luke,
you'll find the following (taken from a 8.2-STABLE/i386
system source tree):

/usr/src/sys/sys/types.h (line 253):

	typedef __time_t time_t;

/usr/src/sys/i386/include/_types.h (line 97):

	typedef __int32_t __time_t;

/usr/src/sys/i386/include/_types.h (line 55):

	typedef int __int32_t;

So it boils down to (int), but %ld expects (long). This
is the exact content of the warning. You can either
case the (time_t) value to (long), or change %ld to %d
to avoid the warning.
