I have a table that one of this record has been changed.
Is there any MySQL function to get the date of this updating?

No. There is no way to get that modification date unless you explicitly stored it somewhere else (through a trigger or application side technique).
Well it depends on how you are using the data value.
but mostly it is a good practice to have both created_at and updated_at as attributes for your table.
OR if you want to keep each update date info for a record then store them in different table. before each update in main table insert existing row in tracking table from main table.
