The Zulu Time Trial — A Proposal

// Global Sky Check

Six cities. One clock. Proof that the number was always the easy part.

// The Premise

Every clock on Earth is already secretly agreeing on Coordinated Universal Time — we just hide it behind local offsets so "8 AM" keeps meaning "coffee," not "stars." Pilots, sailors, the military, and the crew of the ISS have already skipped the offset entirely and run their whole day on Zulu.

Nobody has tried it on an ordinary city's school bells and dinner reservations. That's the actual experiment: not whether Zulu time works, but whether it survives rush hour.

// The Plan

01

One City, Two Weeks

14 Days · Opt-in City

One volunteer city — ideally one already used to juggling time zones for work or trade

Transit boards, shop hours, school bells, and TV listings all switch to Zulu overnight

A small "sun clock" stays posted alongside it for the first three days, then comes down

Anyone can opt out and keep local time — no one gets left stranded at a bus stop

02

The Global Window

30 Days · Opt-in Worldwide

Unlocks only if Phase 01's city would vote to do it again

Open registration — any person, team, or school anywhere can run their calendar in Zulu for a month

Everyone else keeps their normal clock; the experiment lives inside participants' own calendars

Cross-continent meetings stop needing a time zone converter — for participants, at least

// What We Measure

No fake results here — just the four questions the trial is actually built to answer.

Scheduling Friction

Time to lock in a cross-timezone meeting, before the trial versus during it.

Sleep & Rhythm

Daily self-reported sleep quality and energy, tracked against the pre-trial baseline.

Drop-off Rate

How many participants quietly revert early, and on which day they give up.

Would You Keep It

The one question that actually decides Phase 02 — asked plainly, at the end.

// The Vote

If the trial city would do it again, Phase 02 happens. If not, everything reverts and we never speak of it again. Cast a straw-poll vote below to see the bar move — Gun saves the rows when a peer is reachable.

Keep Zulu Time<br>Revert To Local

No votes yet — be the first.

// Known Turbulence

Prayer times and holidays are anchored to the sun and the calendar , not a clock number — those don't move just because the clock does.

Labor law is written in clock hours. "9-to-5" needs a rewrite when 9 could be pitch dark for someone three time zones over.

The date itself gets strange. Since the international date line doesn't move, "today" can flip to "tomorrow" in the middle of your afternoon.

Kids run on daylight and routine , not a display. Phase 01 watches school-age participants especially closely.

// Flight Log (Prior Art)

Aviation, shipping, the military, and the ISS already run entirely on Zulu — this proposal just asks whether an ordinary city could too.

In 2012, two Johns Hopkins professors — economist Steve Hanke and astrophysicist Richard Conn Henry — proposed exactly this for the whole world, confident people would simply learn to attach a new number to breakfast.

China already runs one time zone across a landmass wide enough for five — living proof that the clock number and the sun's position can drift apart without anything falling apart.
