TIMESTAMP_TZ values are compared based on their times in UTC. Operations are performed with the time zone offset specific to each record. When a time zone is not provided, the session time zone offset is used. TIMESTAMP_TZ internally stores UTC time together with an associated time zone offset. TIMESTAMP_NTZ is the default for TIMESTAMP. If the output format contains a time zone, the UTC indicator ( Z) is displayed. All operations are performed without taking any time zone into account. TIMESTAMP_NTZ internally stores “wallclock” time with a specified precision. However, all operations are performed in the current session’s time zone, controlled by the TIMESTAMP_LTZ internally stores UTC time with a specified precision. Snowflake supports three variations of timestamp. TIMESTAMP_LTZ, TIMESTAMP_NTZ, TIMESTAMP_TZ ¶
