on what system are you trying to do this?

On *BSD there's "date -r seconds-since-epoch" (and of course you can
adjust the output format as desired too)

The C code that does this (relavent bits, more or less just cut&pasted
from date.c, with turning it back into a compilable program left as an
excercise to the reader! ;-) is:

	time_t tval;
	char *format;
	char buf[BUFSIZ];
	tval = strtol(epoch_seconds_string, NULL, 0);
	format = "%a %b %e %H:%M:%S %Z %Y";
	(void) strftime(buf, sizeof(buf), format, localtime(&tval));
	(void) printf("%s\n", buf);

localtime() is plain old ANSI C, and strftime() is new to ISO C99 but
old to *BSD.
