Updating MySQL's information_schema

Hi,

I recently migrated MySQL from one disk to another disk. It looks like as a result the informationschema.TABLES.CREATETIME has been updated on multiple InnoDB records to be the date of the migration rather than the correct original dates. I can see the correct date on the file system for the representative .frm files.

-rw-rw----  1 mysql mysql 8.4K Mar 17 17:03 home_201503b.frm

I tried to update informationschema.TABLES.CREATETIME for one of these tables and received an error message.

mysql> UPDATE information_schema.TABLES SET CREATE_TIME='2015-03-17 17:03:00' WHERE TABLE_SCHEMA='foo' AND TABLE_NAME='home_201503b';
ERROR 1044 (42000): Access denied for user 'root'@'localhost' to database 'information_schema'

root has full access.

Is there any way to make this change?

Thanks, Josh
