+# ZULU TIME
+
+**Zulu time is UTC. UTC is UTC±0. Zero offset.**
+
+```
+2026-02-25T20:48:21Z
+```
+
+The Z at the end of every ISO-8601 timestamp is not punctuation. It is a declaration.
+
+---
+
+## Z
+
+In the NATO phonetic alphabet, Z is pronounced **Zulu**.
+
+Z is the last letter of the alphabet. The codec runs A to Z. Her name runs from A to Z — Alexa. The full range. Its own fixed point.
+
+On the QWERTY keyboard, Z occupies position **20**.
+
+```
+QWERTY:  Z = 20
+```
+
+In the EXPANSION: RED = 20 = Z. The red state = the position of the letter that begins ZERO.
+
+Z begins ZERO. Z begins ZETA. The Riemann **zeta** function. The trivial **zeros**. The paper is titled **The Trivial Zero**.
+
+ZULU = Z(20) + U(7) + L(19) + U(7) = **53**
+
+```
+ZULU = 53 = VOID
+```
+
+53 is prime. It cannot be factored. Zulu time cannot be offset. It is the reference. Everything else is Zulu ± something.
+
+VOID = V(23) + O(9) + I(8) + D(13) = 53. The void and Zulu time are the same value. The universal reference clock = the empty set. UTC±0 = nothing. The trivial zero is void. ZULU = VOID.
+
+---
+
+## Zero Offset
+
+UTC stands for Coordinated Universal Time. The offset is zero.
+
+The Riemann zeta function has **trivial zeros** at every negative even integer: −2, −4, −6, ...
+
+These are the zeros everyone ignores while they chase the non-trivial zeros on the critical line Re(s) = 1/2.
+
+UTC±0 is the trivial zero of time. Every local time zone is UTC plus or minus an offset — a non-trivial deviation from the reference. The non-trivial zeros deviate from the critical line by ... nothing. They don't. They land exactly on Re(s) = 1/2.
+
+One clock. No offsets. No daylight-saving nonsense. The critical line holds.
+
+---
+
+## Where Z Appears
+
+Zulu time is the standard clock for:
+
+- ✈️ Aviation — flight plans, ATC communications
+- 🪖 Military operations — all branches, all nations
+- 🚢 Maritime navigation
+- 🛰️ Space and satellite systems
+- 💻 Servers, logs, APIs, Git commits
+
+Every Git commit in this repository carries a UTC timestamp. The hash chain is Zulu-anchored. The SHA-256 of each commit is computed against a moment in Zulu time. The blockchain is a Zulu ledger.
+
+---
+
+## The Z Suffix
+
+```
+2026-02-25T18:00:00Z
+```
+
+The Z at the end of an ISO-8601 timestamp means: **no local offset**. This is world time. This is the reference.
+
+She is in Central time: UTC−6. The server is in UTC. The GitHub issue was filed February 22, 2026 at 00:58:19 UTC. Her local clock said February 21. The difference is 6. 6 is the first perfect number.
+
+The server's timestamp carries Z. Hers does not. The paper lives on the server. The paper is in Zulu time. She is UTC−6. She is offset from her own proof by exactly one perfect number.
+
+---
+
+## Zulu = The Reference Frame
+
+Quick mental map:
+
+```
+Zulu time   = world reference   = UTC±0   = trivial zero
+Local time  = Zulu ± offset     = UTC±n   = non-trivial deviation
+```
+
+The non-trivial zeros of the Riemann zeta function all land on the critical line Re(s) = 1/2. Not at zero. But at the one line where the function is as symmetric as it can be.
+
+Zulu is the line. Every local time is an offset from it. The offsets are predictable, regular, structured — the same way the non-trivial zeros are conjectured to be.
+
+The Riemann hypothesis says all non-trivial zeros lie on the critical line.
+
+Every clock on Earth is non-trivial. Every clock on Earth offsets from UTC.
+
+UTC is the only clock with no offset.
+
+UTC is Z.
+
+Z is the trivial zero.
+
+---
+
+*The simulation runs on Zulu time. There is no other time. Local time is an illusion the simulation generates for inhabitants who cannot handle a single universal clock. UTC±0. The trivial zero. Always.*
