This involves making sure that the timestamp is within 15 mins of "now" to be accepted. This has other rollover effects in that I don't send an "old" C record on startup anymore, just send an A record followed by a K. These days a newly minted C record will be along in 15mins or so anyway. Made sh/newc terminal width aware. Added CTY-1709 cty.dat data.
