For tz-link.htm you write:

Please see <http://www.astrologyschool.com/nztime.html>.

Please see <http://www.bom.gov.au/climate/averages/tables/dst_times.shtml>.

> The link http://www.nationalatlas.gov/timeznm.html does not exist

Yes, thanks, I found that one just a few hours ago myself.  I'll
propose a patch for these (and other) problems soon.
