Module floor 

The anti-rollback time floor.

No time reported by a Roughtime server (or the OS clock) is trusted below this floor: a machine cannot legitimately observe a time earlier than when this crate was built, and HARDCODED_FLOOR_SECS is a belt-and-suspenders lower bound baked directly into source.

By default (the build-time-floor feature disabled) the effective floor is simply HARDCODED_FLOOR_SECS — a static value with no dependency on the build machine’s clock, keeping builds reproducible. Enabling build-time-floor additionally ratchets the floor forward to the start (UTC) of the day the crate was built, at the cost of build reproducibility — see build.rs for the mechanism and the crate-level docs for guidance on which mode to pick.

Constants

EFFECTIVE_FLOOR_SECS

The effective anti-rollback floor: the later of HARDCODED_FLOOR_SECS and the build-time floor (which is 0 — a no-op — unless the crate was built with the build-time-floor feature enabled).

HARDCODED_FLOOR_SECS

The absolute, hardcoded anti-rollback floor: July 1, 2026 00:00:00 UTC, in Unix seconds.

Functions

check_floor

Rejects a candidate Unix timestamp (in seconds) that predates EFFECTIVE_FLOOR_SECS.
