Variable: CHALLENGE_CLOCK_SKEW_MS

const CHALLENGE_CLOCK_SKEW_MS: 30000 = 30_000

Defined in: proof.ts:28

How far past expiresAt (milliseconds) a challenge is still presented to the wallet. The gateway's clock decides expiry, and this client's may run a little ahead of it, so a challenge that only just expired by the local clock is not refused here. Anything older cannot be accepted and is refused before the wallet prompt.
