Summary: in this tutorial, you will learn how to use the PostgreSQL MAKE_TIME() function to create a time value from hour, minute, and second values.

The MAKE_TIME() function allows you to create a time value from hour, minute, and second values.

Here’s the syntax of the MAKE_TIME() function:

MAKE_TIME ( hour int, min int, sec double precision ) → time

In this syntax:

• hour: The hour part of the time. The valid range for the hour is from 0 to 23. 0 represents midnight (12:00 AM) and 24 represents noon.
• min: The minute part of the time. The valid range for the second is from 0 to 59.
• sec: The second within a minute. Its valid range is from 0 to 59.999999.

The MAKE_TIME() function returns a time value constructed from the hour, min, and sec.

If you use invalid values for hour, min, and sec, the function will issue an error.

Let’s explore some examples of using the MAKE_TIME() function.

The following example uses the MAKE_TIME() function to construct a time 22:30:45 from hour, minute, and second:

SELECT MAKE_TIME(22,30,45);

Output:

 make_time
-----------
 22:30:45
(1 row)

The following example attempts to use invalid values for hour, minute, and second to construct a time and results in an error:

SELECT MAKE_TIME(25,30,45);

Error:

ERROR:  time field value out of range: 25:30:45

Even though the type of hour and minute parameters are integers and seconds are double precision, you can pass string arguments to the MAKE_TIME() function.

Behind the scenes, the function will implicitly convert these string arguments to the proper types, as long as the results of the conversions are in the valid range.

SELECT MAKE_TIME('8', '30', '59.999999');

Output:

    make_time
-----------------
 08:30:59.999999
(1 row)
