Should any change or error in the records be discovered or result in any member, retiree,
survivor or beneficiary receiving from the retirement system more or less than he
would have been entitled to receive had the records been correct, the board shall
have the power to correct such error, and as far as possible, to adjust the payments
in such manner that the actuarial equivalent of the benefit to which such member,
retiree, survivor, or beneficiary was properly entitled is paid.
