I've updated your code to do this.

	/*
	 * if time_t is 32 bits, then
	 * the "End of Time" is Mon Jan 18 22:14:07 2038
	 * This code copes with that. Sort of.
	 * Why do we do this? Sometimes RTC's screw up or are badly set.
	 */
	/* is time_t a 4 byte quantity? */
	if(sizeof(time_t) <= sizeof(int32_t)) {
		if(yr >= 138) {
			printf("WARNING: RTC time at or beyond 2038.\n");
			yr = 137;
			printf("WARNING: year set back to 2037.\n");
			printf("WARNING: CHECK AND RESET THE DATE!\n");
		}
	}

I'll be committing it on port-i386 fairly soon.
