Help me settle a friendly argument. When everyone agrees with me, I'll tell you which side I'm on.

When a client tells you they need an order by a certain date, do you take that to mean that you can enter it on that day, or that you need to get it done the day before, so that it's there for the beginning of business when they arrive.
Example: Order needed by January 12, 2008 (No time given)
Do you get it done on the 11th, or get it in to them on the 12th?
Told you it was stoopid.
ETA: I'm not referring to getting the order entered for your own comfort level, but getting it to them on the day when they expect it. Do you think they expect it to be there when they turn on their computers the next day, or do they expect it to get there sometime that day?
See... stoopid.
