In the results, the first half of the output depicts the time in 24hr format. The function takes an optional argument, called precision. The LOCALTIME() function returns the current time without the local time zone. We see here along with the user provided data, the audit column was also populated with the current timestamp. Let us now insert a record in the table INSERT INTO registration(student_name)

Registration_datetime TIMESTAMP DEFAULT LOCALTIMESTAMP In this table, registration_datetime is the audit column. Let us take the following example to understand the scenario. In programming world the LOCALTIMESTAMP function is often used to insert default values in columns that track the current date and time for the records inserted, for example in audit columns. In this example, numeric 2 value of the precision passed in the argument, therefore up to 2 decimal places are returned in the output. Since no precision is provided as an argument, up to 6 decimal places are returned. The results of the first half of the output depict the date followed by time in 24hr format. The basic syntax is: SELECT LOCALTIMESTAMP

The LOCALTIMESTAMP() function returns the current date and time without the local time zone.
