-- V015__create_local_timezone_views.sql
-- UDT-011: Vistas admin con OccurredAt convertido a hora Argentina.
--
-- Crea:
--   dbo.v_AuditEvent_Local   — AuditEvent con OccurredAtLocal (offset -03:00)
--   dbo.v_SecurityEvent_Local — SecurityEvent con OccurredAtLocal (offset -03:00)
--
-- Conversión: OccurredAt AT TIME ZONE 'UTC' AT TIME ZONE 'Argentina Standard Time'
--   → offset fijo -03:00, sin DST (Argentina dejó el horario de verano en 2009).
--   → Nombre 'Argentina Standard Time' es portable: Windows + SQL Server Linux 2022+ (via ICU).
--
-- Idempotente: re-ejecutable. Guard IF OBJECT_ID IS NULL en cada vista.
-- No altera tablas base — rollback seguro sin pérdida de datos.
-- Reversa: V015_ROLLBACK.sql.
-- Run on: SIGCM2 (dev) y SIGCM2_Test (integration tests).
--
-- Covers: REQ-DB-VIEWS-001, REQ-DB-VIEWS-002, REQ-DB-VIEWS-003, REQ-DB-VIEWS-004
