pub const GNSS_TIME_TRUST: u32 = 4870;Expand description
Whether receiver-derived time may set the wall clock
(PROP_GNSS_TIME_TRUST) — BOOL, default 1. Cleared, neither a fix
nor a receiver-RTC read touches PROP_TIME, which leaves a
manually-set clock proof against a jammed or spoofed sky. Position
reporting is unaffected. Requires CAP_GNSS.
