in `validators(b.Header.NextValidatorsHash)` is correct until time `b.Header.Time + TRUSTED_PERIOD`.
*Assumption*: "correct" is defined w.r.t. realtime (some Newtonian global notion of time, i.e., wall time),
while `Header.Time` corresponds to the [BFT time](./../bft-time.md). In this note, we assume that clocks of correct processes
while `Header.Time` corresponds to the [BFT time](../consensus/bft-time.md). In this note, we assume that clocks of correct processes
are synchronized (for example using NTP), and therefore there is bounded clock drift (`CLOCK_DRIFT`) between local clocks and
BFT time. More precisely, for every correct light client process and every `header.Time` (i.e. BFT Time, for a header correctly
generated by the Tendermint consensus), the following inequality holds: `Header.Time < now + CLOCK_DRIFT`,
