Information_Schema are views and read-only. Yo can not update meta data about tables, only by modifying actual table with
ALTER TABLE. If you do an
ALTER TABLE you will have current timestamp in meta data.
INFORMATION_SCHEMA is a database within each MySQL instance, the place
that stores information about all the other databases that the MySQL
server maintains. The INFORMATION_SCHEMA database contains several
read-only tables. They are actually views, not base tables, so there
are no files associated with them, and you cannot set triggers on
them. Also, there is no database directory with that name.
Although you can select INFORMATION_SCHEMA as the default database
with a USE statement, you can only read the contents of tables, not
perform INSERT, UPDATE, or DELETE operations on them.
