Our retail POS computer's clock change its date and time to later date, and the cashier did not notice that the date and time of the computer is not correct and the cashier already transacted many retail transaction.
1. How to correct the date and time of the transaction?
2. Is there's a way to prevent this from happening again?
Example:
Correct date and time is 06/03/2018
Date and time during the transaction in the Retail POS computer was 06/01/2018
All the transaction was registered in the 06/01/2018 that should be in the 06/03/2018
Thanks in advance.
