The MySQL SYSDATE() function returns the current date and time. The value is returned in ‘YYYY-MM-DD HH:MM:SS’ or YYYYMMDDHHMMSS format, depending on whether the function is used in a string or numeric context.
This function is similar to NOW() but with a subtle difference. SYSDATE() returns the time at which it executes. NOW() returns the time at which the statement started executing.

The MySQL NOW() function returns the current date and time. The value is returned in ‘YYYY-MM-DD HH:MM:SS’ or YYYYMMDDHHMMSS format, depending on whether the function is used in a string or numeric context.
Here’s how it works.

In MySQL, the CURRENT_TIME function can be used to return the current time.
This function is actually a synonym for CURTIME() which returns the current time, so you can choose which function you prefer to use.

In MySQL, the CURTIME() function is used to return the current time.
More specifically, it returns the current date as a value in ‘HH:MM:SS’ or HHMMSS format, depending on whether the function is used in a string or numeric context.

In MySQL, you can use the ADDTIME() function to add a specified amount of time to a time or datetime expression.
Examples of this function below.
The difference between the MySQL SUBDATE() and DATE_SUB() functions is exactly the same as the difference between the ADDDATE() and DATE_ADD() functions. One function allows for two different syntax forms, whereas the other allows for just one.
This article demonstrates the difference.
