The gzipped versions of the new data files are corrupt; the corruption appears to be introduced by gzip. So, for now, you'll find ftp://elsie.nci.nih.gov/pub/tzcode2002a.tar and ftp://elsie.nci.nih.gov/pub/tzdata2002a.tar available for downloading until I figure out what's going on with gzip. Thanks to Bradley White for catching the problem! --ado
