The `localtime()` function returns the given epoch timestamp (or now,
if omitted) as a dictionary containing broken-down date and time
information according to the local system timezone.

-- Testcase --
{%
	let t = time();
	let d1 = localtime();
	let d2 = localtime(1647953502);

	// assert that localtime without epoch returns the current time
	let c = timelocal(d1);
	assert(c >= t && c <= t + 5, "localtime() result does not match time()");

	// dump fixed time and check expected output
	printf("%.J\n", d2);
%}
