At the start of every shift we look back through all of our orders to verify that they match the MAR and that no labs/ tests ordered were not completed. I have found discrepancies more than once that are days old ( yes, this means some people are skimping on the chart check). If you are signing an order off with the current time and date then it is not illegal. You are not saying you did it when it was written. You are saying I see it now and it was implemented as written.
