TIMESTAMP_TZ values are compared based on their times in UTC. If the string does not have a time component, midnight will be used. In certain cases, such as string-based comparisons or when a result depends on a different timestamp format than is set in the session parameters, we recommend explicitly converting values to the desired format to avoid unexpected results.

There are 3 different timestamp types in Snowflake: To Here is an example of changing a TIMEZONE at the session level: The output shows the current value is set at the session level, and its different from the default value: In the following article, we will discuss different timestamp types available in Snowflake and use cases for each: TIMESTAMP_NTZ (Timestamp without Timezone): TIMESTAMP_NTZ is the datatype for timestamps without a timezone (ntz = no time zone). Snowflake supports a single DATE data type for storing dates (with no time elements). This data type combines date and time into a single entity and is thus very useful. (For details, see TO_TIMESTAMP / TO_TIMESTAMP_*.) TIMESTAMP_TZ internally stores UTC time together with an associated time zone offset. Use the following steps to create a linked service to Snowflake in the Azure portal UI. Converting unix timestamp string to readable date.
