[PATCH] show_date(): fix relative dates

We pass a timestamp (i.e. number of seconds elapsed since Jan 1 1970,
00:00:00 GMT) to the function. So there is no need to "fix" the
timestamp according to the timezone.

	Just compile & run this little test program to see what I mean:

	#include "cache.h"

	int main(int argc, char **argv)
	{
		time_t t = time(NULL);
		printf("%s\n", show_rfc2822_date(t, 100));
		printf("%s\n", show_date(t, 100, 0));
		printf("%s\n", show_date(t, 0, 0));
		printf("%s\n", show_date(t, 100, 1));
		printf("%s\n", show_date(t, 0, 1));
		return 0;
	}

	Here, it outputs this:

	Sat, 20 Jan 2007 22:20:42 +0100
	Sat Jan 20 22:20:42 2007 +0100
	Sat Jan 20 21:20:42 2007 +0000
	in the future
	0 seconds ago

	Noticed that "in the future"?
