 * Checks if the given value is a Date object in the future.
 *
 * Beware that the behaviour of this check depends on the current time and can thus be difficult to test. In particular,
 * as time goes by the property can become invalid without ever changing its value.
 *
 * #### Example
 * ```typescript
 * // Ensure the value is in the future.
 * @FutureDay()
 * scheduledFor: Date
 * ```
 *
 * @category Date
 * @param options Generic class-validator options.
