A quick search for "HDT" on the Github repo points to zdump.8 and tz-how-to.html, as well.
Thanks for catching that. I saw other ways the doc doesn't match the latest data and fixed them too, in the attached proposed patch. While doing this I noticed to my surprise that tz-how-to.html already documented HWT and HPT! No clairvoyance was involved; it turns out that older versions of tzdb used those abbrevations. HWT/HPT was changed to HST in 2011 in the changes proposed in <https://mm.icann.org/pipermail/tz/2011-August/008703.html> with the commentary being "Avoid unnecessary use of US rule in America/Honolulu". Perhaps Arthur didn't notice that although the patch didn't affect UT offsets it changed abbreviations? Anyway, there does seem to be have been use of the phrase "Hawaiian War Time" for timekeeping in Hawaii during World War II, so HWT/HPT does seem to be more historically accurate. A quick Google Books search found these two occurrences: The Hawaiian Journal of History, Volumes 26-27, page 221, "The new time quickly became known as 'Hawaiian War Time.'" Deignan DD. The Shadow of Sacrifice: The True Story of a Pearl Harbor Survivor and his Nephew and Namesake (2016), p 236. "At about 4:20 PM, Hawaiian War Time, on Friday, March 20, 1942, P.F.C. Joseph J. Deignan was buried with full military honors ..."
