Get the Time of Last update of a column

This command gives the date of the last update for a table SELECT UPDATE_TIME FROM information_schema.tables WHERE TABLE_SCHEMA = 'MyDB' AND TABLE_NAME = 'MyTable' But I want to find the time of last update of a particular column of a table. I can't use triggers because I want to know the time of last update of a specific column from a system table. I hope I explained well my problem.
