adding timestamp to debug messages

>+#include <sys/timeb.h>

style(9) says this should go with the other <sys/...> includes. 

>+		ftime (&tb);

ftime is obsolete and has been removed from POSIX.1-2008.  Should use
gettimeofday instead.

>+		localtime_r (&tb.time, &tm);
>+		p += strftime (p, 16, "%Y%m%d.%H%M%S", &tm);

I'm not a fan of unnecessary pointer arithmetic.  Since this is neither
time nor space critical, I'd rather strftime into a static buffer then
use snprintf to assemble the final string.

>+		p += sprintf (p, ".%03d ", tb.millitm);

also not a fan of unbounded string functions even if this particular
one is safe.
