Is it not the right procedure for administration & personnel department to verify the school certificate with regards to the D.O.B at the time of joining and issue a confirmation letter of the same to ward off discrepancies in personal data and close the matter ones for ever ?

There are innumerous cases where there are no such records or even if there are such records, the records are not true ( mostly because of ignorance of the parent generation). There are norms stipulating a specified period within which any government employee can request a change in the D.O.B, if noticed to be incorrect. The onus is on the employee since he/she is the one who gives the first declaration regarding his/her DOB, sir.
