Annotation equivalent

Pass an ISO-8601 string. Both date-only and full date-time formats are accepted.

import dev.ditsche.teki.annotation.Before;

public class SubmissionRequest {
    @Before("2026-01-01")
    private LocalDate deadline;

    @Before("2026-01-01T00:00:00Z")
    private Instant cutoff;
}

LocalDate strings ("2026-01-01") are interpreted as the start of that day in the system default timezone. Use a full offset string ("2026-01-01T00:00:00Z") to pin to a specific instant.
