<p>I have been using tzdata in one form or another for 3 decades
and have always been puzzled why Dallas or Houston Texas were
never listed as an alias to America/Chicago. Dallas-Fort Worth
is currently the 4th largest city in America and Houston is
5th. Is there some particular reason for these omissions? Or
is it just that no one ever volunteered to do the work to get
them added? Additionally I have never seen El Paso Texas
listed even though it is the one spot in Texas that is in the
Mountain Time Zone.</p>
<p>I know that Chicago has been the Central Time Zone marker as
far back as I can remember (at least 1970).<br>
