![]() The timestamp data type is more readable. Similarly, a timestamp can be converted to a date using the CAST operator, as shown in the following code snippet: SELECT CAST(' 20:41:12. In our example, the text date and time ' 7/15:23:45'was converted to the timestamp value 15:23:45+02. The CAST operator in Postgres allows us to convert one data type to another. 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. Experts, I have this column I used the following to calculate the time difference between two time stamps: x.created::timestamp at time zone 'America/LosAngeles' - usr. 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).Literally speaking the epoch is Unix time 0 (midnight ), but 'epoch' is often used as a synonym for Unix time. The PostgreSQL formatting functions provide a powerful set of tools for converting various data types (date/time, integer, floating point, numeric) to formatted strings and for converting from formatted strings to specific data types. DD represents a 2-digit day of the month. The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since Janu(midnight UTC/GMT), not counting leap seconds (in ISO 8601: ).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 For brevity, these variants are not shown separately. Let’s convert a string containing date, time, and time zone information to the timestamptz data type. All the functions and operators described below that take time or timestamp inputs actually come in two variants: one that takes time with time zone or timestamp with time zone, and one that takes time without time zone or timestamp without time zone. You’d like to convert a string containing datetime information to a timestamp in PostgreSQL.
