The TZdata file I grabbed from the server an NIH (and 
expanded/extracted, with tar) contains three files of html and one is 
NorthAmerica.  So, I am confused as to using that in my usr/share/zoneinfo
My system still reports April 1:  will the html be read correctly, and 
is it inefficient to go that route of using an html file?
