How to insert current_timestamp into Postgres via Python?17 Mar 2025 | 2 min read PostgreSQL supports two types of data to process timestamps: time stamp and timestamptz. Timestamp data type allows us to create a timestamp that is not based on the timezone. Likewise, timestamptz can help us create a timestamp with the timezone. It is possible to store dates and times using the datatype timestamp. It does not, however, include time zone information. This means that if you change the timezone of your database server, the values for timestamps stored in the database won't immediately update, and in these circumstances, the datatype timestamptz is used. Example:The code below illustrates the datatypes. psycopg2.connect() technique is utilized to connect with the database. A cursor can be created by connection.cursor() method. connection.cursor() method. execute() method executes the SQL commands specified. A table called timestamp_data is made. A time stamp formatted in a string is added to the table that is created. The values are then retrieved from the table. The table is where we see the column timestamp_timezone as well as the timezone. Output:  Next TopicHow to Perform a One-Way ANOVA in Python |
