We have the following Timestamp functions such as NOW(), CURRENT_TIMESTAMP, CURRENT_TIME, TIMEOFDAY(), converting time value into a different time zone using the timezone(zone, timestamp) function on time values available in the PostgreSQL, which help us to enhance the performance while we are using the timestamp data type. Note: Usually, we will use the timestamptz datatype to store the timestamp data values as it is always a good exercise.
