In other words, 2025-01-01T00:00+02:00 was NOT Europe/Paris (as it was CET at that time, GMT+1), 2024-08-01T00:00+02:00 could have been Europe/Paris (CEST, GMT+2), 2030-08-01T00:00+02:00 may be Europe/Paris (CEST, GMT+2), or perhaps not (CET, GMT+1). Or it may be a completely different TZ that incidentally shares the same offset at that time.
