Computer time fall to year 2012

Hello yesterday we had electrical blackout … our computer time fall to year 2012 , and our staff did not notice and keep using sambapos, when we end workperiod , its only show few records , i try to correct the data from Table “AccountTransactionValues” using SQL Server Management Studio …but still can get it right is there anyone can help me to fix this thanks before

At this point it’s best to notate that day and record the year and time period for the mistake for accountant but don’t try to change it. Just move forward. If you need to fix cash etc then just do some account transactions in corrections account to fix balances.
