Thanks for the link updates. I'll let Arthur handle the tz-art.htm change. For tz-link.htm you write:

The link http://www.astrologyhouse.co.nz/timechanges.htm does not exist anymore, and I can not find a relocated page at the web site.

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

The link http://www.lawlink.nsw.gov.au/crd.nsf/pages/time2 does not exist anymore, and I can not find a relocated page at the web site.

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

The link http://www.nationalatlas.gov/timeznm.html does not exist anymore. http://nationalatlas.gov/mld/timeznp.html seems to be a suitable replacement.

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