Let us first list out all available databases and then switch o a database named educational_platform by using \list and then \c educational_platform. And then, change the time zone of the database server and check the outputs. Check the current timezone and insert one record in the above table and check its value. We will prepare one table with two columns, one with the timestamp and another with timestamptz. To understand working more clearly, let us consider one example. It is used to retrieve data in years, months, days, and time formats and adjust the interval. It is used to test whether the supplied value, that can be either timestamp, interval, or date, is finite or infinite. It is similar to date_part and is used to retrieve the value of a particular field from the given timestamp or interval, whichever source is specified. It is used to get a particular value from the date, for example, a year or just a month or whichever field value from the source timestamp or interval. It is used to get the current date according to the database’s timezone and settings. To get the difference between a particular timestamp and a current timestamp or the difference between two timestamps in the form of years, months, and days. There are many functions available for the date and time manipulation. The same is the case with the storage of time and timetz. The server subsequently converts this value to the appropriate time zone, typically determined by the time zone setting either in the database server or set by the user, depending on the time zone of the current database connection. The PostgreSQL database server retrieves the UTC value from the table when attempting to fetch a specific value. Whenever we try to store any value in the timestamptz datatype value, then it is automatically converted into its corresponding UTC value, and then its UTC value is stored in the database table. In the case of timestamptz data typed values, the time zone is also considered, and the value is stored in the UTC format. Timestamp allows us to store the date as well as the time. Time can be stored along with zone consideration in the database It is used to store only time value in datatbase ![]() Used to store the time intervalin database Used to store date and time along with the timezone consideration Used to store the date and time togetherly Hadoop, Data Science, Statistics
