```

| Field               | Value           |
| ------------------- | --------------- |
| Selector            | `0x97a4064f`    |
| Canonical signature | `effectiveAt()` |

## Description

Returns the timestamp at which the pending UI multiplier becomes effective. This is part of the ERC-8056 required extension (`0x4bd27648`), alongside `newUIMultiplier()`.

When no pending update is scheduled, the value is not meaningful; pair this call with `newUIMultiplier()` to determine whether a pending update exists.
