442# From Paul Eggert (2018-10-25):
443# On 1921-03-04 federal law placed all of Texas into the central time zone.
444# However, El Paso ignored the law for decades and continued to observe
445# mountain time, on the grounds that that's what they had always done
446# and they weren't about to let the federal government tell them what to do.
447# Eventually the federal government gave in and changed the law on
448# 1970-04-10 to match what El Paso was actually doing. Although
449# that's slightly after our 1970 cutoff, there is no need to create a
450# separate zone for El Paso since they were ignoring the law anyway. See:
451# Long T. El Pasoans were time rebels, fought to stay in Mountain zone.
