Start by reproducing io.debezium.connector.postgresql.RecordsSnapshotProducerIT.shouldSnapshotTimeArrayTypesAsKnownTypes in the reported Singapore timezone and inspect RecordsSnapshotProducerIT.assertReadRecord at line 319. Compare the expected and actual timetza values and trace the timezone handling involved. Done means the test passes consistently in that environment without breaking the reported timestamp expectations.
