Postgresql timestamp current time11/9/2023 For instance, in India, the timezone difference with UTC is 5 hours 30 minutes. You can even make compound interval statements. To get only the date part, you can run the following command − SELECT (current_date + interval '3 days').date Because interval comparisons are made on timestamps. Notice how the output here also contains the time component. Output SELECT current_date + interval '3 days' You can also do these operations on date instead of timestamps SELECT current_date At the time of writing this, the output was − 10:57:13.28955+00 SELECT current_timestamp - interval '5 hours' Now, what if you want the relative time instead of the current time? For example, if you want the time corresponding to 5 hours prior to the current time, you can get it using intervals. The output will look like the following − 15:52:14.738867+00 You do that as follows − SELECT current_timestamp currenttimestamp is a system function returning a timestamp representing the point-in-time at which the current transaction started. In this tutorial, you have learned how to use the PostgreSQL CURRENT_TIME function to get the current time.Quite often, you need the current timestamp in PostgreSQL. Third, check whether the row was inserted into the log table with the created_at column populated correctly by using the following query: SELECT * FROM log Īs you see, the created_at column was populated with the time of which the INSERT statement executed. In the statement, we only specified a value for the message column, therefore, other columns got the default values. VALUES( 'Testing the CURRENT_TIME function') Code language: JavaScript ( javascript ) Second, insert a row into the log table: INSERT INTO log( message ) The log table has the created_at column whose default value is the result of the CURRENT_TIME function. The CURRENT_TIME function can be used as the default value of TIME columns.įirst, create a table named log for the demo: CREATE TABLE log ( The following example illustrates how to use the CURRENT_TIME function with the precision set to 2: SELECT CURRENT_TIME( 2) Code language: SQL (Structured Query Language) ( sql ) In this example, we didn’t specify the precision argument, therefore, the full precision available included in the result. (1 row) Code language: SQL (Structured Query Language) ( sql ) The output is a TIME WITH TIME ZONE value as follows: timetz The following example shows how to get the current time: SELECT CURRENT_TIME The CURRENT_TIME function returns a TIME WITH TIME ZONE value that represents the current time with time zone. If you omit the precision argument, the result will include the full available precision. The precision argument specifies the returned fractional seconds precision. The CURRENT_TIME function accepts one optional argument: Literally speaking the epoch is Unix time 0 (midnight ), but 'epoch' is often used as a synonym for Unix time. The following illustrates the syntax of the CURRENT_TIME function: CURRENT_TIME(precision) Arguments 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: ). The PostgreSQL CURRENT_TIME function returns the current time with time zone.
