从元数据中检索MySQL行创建的时间戳?

我一直在维护一个MySQL表，该表包含从PHP代码插入的数据行，大约有一年半的时间.我知道这真是愚蠢，我没有包含用于插入这些行的timestamp.

I have been maintaining a MySQL table of rows of data inserted from PHP code for about a year and a half. Really stupid, I know, I didn't include the timestamp for insertion of these rows.

是否可以通过某种元数据或其他方式检索创建这些行的timestamp? (是MySQL还是PHPMyAdmin或其他一些可能的方式?)

Is there any possible way that I can retrieve the timestamp of creation of these rows through some metadata or some other way? (Of MySQL or PHPMyAdmin or some other possible ways?)
