To avoid potential confusion to folks who may read a speculative patch such as this — perhaps years into a future where this may have all come to nothing — it is much clearer for now to say here that it's just a bill.

Several copies of similar bills for permanent DST and permanent standard time have been introduced into both the House and Senate during each Congress for some time now. Legally they are all distinct. H.R. 139 is the only one in this Congress that has passed one chamber, so it is "ahead" of any of the others at this stage.

On the contrary, as is stated in the commentary, this diff is somewhat intentionally maximalist so that folks can prepare for potential changes to the most zones that might be affected by this bill and its potential knock-on effects if other jurisdictions follow suit. In some cases this is just abbreviations switching to numeric, but in many others assumptions have been made for the sake of exposition. Many other end-state configurations are possible and, indeed, likelier.

We will certainly want to test several different speculative versions over the coming weeks. In particular, even if Canadian and Caribbean jurisdictions don't change their timekeeping practices, the US' change would still massively affect the traditional North American abbreviation system in ways that could affect those zones anyway. -- Tim Parenti
