Actually, no. We never change Time or Expense entries "retrospectively". Once you hit the Save button for the first time, after creating it, the fields are locked in. The reason for this is that say in 2011 your billing rate was $95 per hour. In 2012 you decided to raise it to $100 per hour. You would *not* want the old entries changing from 95 to 100 as that would invalidate all your old billing and invoices. If you were audited, you would need to have the correct info. So that is why it is locked in when it is created.
