Core told time eight ways: Date.now() in most layers, JulianDate.now() for
flights and military, Cesium's clock frozen at page load for the sky, the
weather clock for observed imagery. They now read one clock,
src/time/worldClock.js, exported as ./time.
Live is a mode, not a timestamp: while live the clock is the wall clock,
so every layer draws as before. Away from live only the layers that follow
the clock move with it. The weather products follow it, as they followed
the weather transport; a host opts others in with follow(id).
- The weather clock takes its time from the world clock and drives its
replay, stepping its frames as before.
- Satellites, launches, flights and military (still 30 s and 15 s behind),
transit, GNSS, Recent Imagery, street level, the HUD and the celestial
ring read worldTimeFor(id). Cadences stay on the wall clock.
- Cesium's sky (stars, sun, moon, atmosphere, lighting) draws at the world
time each frame instead of the moment the page loaded.
- Weather frames and satellites declare coverage() for a host's timeline.
Knip, configured with the application, package exports, scripts, QA
harnesses, workers, tools and tests as entry points, reports exports
that no module imports. Each was checked by hand against string-based
and namespace imports.
- Symbols that are still used inside their own module lose only the
`export` keyword (176 constants and helpers).
- Unused re-exports are removed from barrel modules (flight, military,
vessel, CCTV, directions, transit history, local ADS-B and street-level
policy modules).
- Declarations that nothing uses at all are deleted, among them
AIS_WATCHDOG_STATUSES, applyFilter, isRadioCountryCode, compactText,
DENSITY_STOPS, the unused CCTV endpoint constants, and the SDR band
constants.
- Default exports that nothing imports are removed. The ones in
src/data/earthquakes.js, src/data/telegeographySubmarineCables.js,
src/data/wind.js and src/data/bhoteKoshiLocator.js each constructed a
layer instance at import time that nothing used; those instances are
no longer created.
Every export of a package.json entry stays, as does TOMTOM_CREDIT,
which the traffic layer reads from the credits namespace it is given.
