... the only way I can think that this happened is that the cell towers were updated prematurely.
More likely, people are using phones with older Android releases that have obsolete time zone data. A device based on tz2014j or earlier should exhibit the bugs mentioned in the WSJ article. Although I don't know how to map tz release numbers to Android release numbers, patches such as this one: https://android.googlesource.com/platform/libcore/+/android-cts-5.0_r4 indicate that Google was laboring as late as December 2015 to push tz2015a through its delivery pipeline, and undoubtedly many Android phones run software older than that. Plus, many people don't update their phones at all. Ironically, just today I gave a lecture on how to shorten cycle times in software pipelines when doing continuous delivery. Perhaps I should follow up next week using tzdata as a case study....
