The set_clock quick-fix pushed the time via POST /clockTime and reported
success unconditionally. On real hardware (ST10, observed live) the firmware
dispatches POST /clockTime to its read handler (HandleClockGetTime) and
ignores the value: it returns 200 but the clock never moves, so the fix was a
silent no-op that still claimed success.
Now setSpeakerClock:
- tries HTTP POST /clockTime (works on firmware that honours it), then
- verifies by re-reading /clockTime; if the clock did not move, it
- sets the clock over SSH (`date -u -s …`, with a BusyBox positional
fallback) on an SSH-reachable speaker (root, empty password), and
- verifies again. It only reports success when the clock actually changed;
otherwise it returns an honest error pointing at the real root cause
(the speaker can't resolve/reach NTP, so the clock is stuck — restore
DNS/NTP reachability; a wrong clock breaks HTTPS/TLS).
The HTTP request format itself was already correct (the device's own GET uses
`utcTime`); the problem was never the payload, only that some firmware has no
HTTP setter at all. Durable NTP-side fix (AfterTouch resolving/serving NTP) is
tracked separately.
