To format a timestamp, specify a timestamp and a valid format as arguments to the TO_CHAR() function: TO_CHAR(TIMESTAMP, format) This post demonstrates how to utilize the TO_CHAR() function to format a timestamp in Postgres. The TO_CHAR() is one of the data type formatting functions that assist us in converting/formatting the data from one type to another. The timestamp data type is more readable.PostgreSQL supports various built-in functions to deal with the timestamp values efficiently, such as CURRENT_TIMESTAMP, TO_TIMESTAMP(), DATE_PART(), etc. In our example, the text date and time ' 7/15:23:45'was converted to the timestamp value 15:23:45+02. The function TO_TIMESTAMP() returns a timestamptz value with time zone information. Notice that the input format is a string. You can find a complete list of datetime pattern elements in the PostgreSQL documentation. Note that we use slashes (/) as date part delimiters and colons (:) as time part delimiters.

ss represents a 2-digit second (from 00 to 59).MI represents a 2-digit minute (from 00 to 59).

HH24 represents a 2-digit hour (from 00 to 23).

DD represents a 2-digit day of the month.

Here are the main elements from the above pattern: The input format indicates how the characters in the string should be converted. This function takes two arguments: a string containing a date and time (in our example, the text ' 7/15:23:45') and the input format (in our example, ‘ YYYY/MM/DD/HH24:MI:ss’). Use the PostgreSQL function TO_TIMESTAMP() when you want to convert a string containing date and time data to the timestamp data type. Here’s the result of the query: new_timestamptz Let’s convert a string containing date, time, and time zone information to the timestamptz data type. You’d like to convert a string containing datetime information to a timestamp in PostgreSQL.
