1040 - 8879 Invalid Signature Date

When I am verifying a return, the following error message appears: ‘FRM 8879 PIN Signature Date Invalid’

This issue can occur if an invalid signature date is entered on the 8879, or if the date or time on the computer’s system clock is incorrect.

Typically, the date should reflect the time of the filing, but also verify the date entered is not a future date.
