Sure, sprintf()...

assuming a filled-in struct ffblk F:

	sprintf(buf, "%02d/%02d/%02d %02d:%02d",
		(F.ff_fdate >> 5) & 0xf,
		F.ff_fdate & 0x1f,
		(F.ff_fdate >> 9) + 80,
		(F.ff_ftime >> 11) & 0x1f,
		(F.ff_ftime >> 5) & 0x3f);

Of course, also assuming American date format :-)

Another interesting (hidden) function is:
	extern long pascal __DOSTIMETOU(unsigned date, unsigned time);
which takes a MS-DOS directory date/time and turns it into a Un*x-like
time value.
