T minus zero means out of time. This comes from a countdown convention used in by both the American military and NASA. Generally, it is used when counting down to a major event that will happen at a specific time. Mathematically, T is time, minus whatever amount of time is left until the event happens.

The Universal Product Code (UPC) is a barcode symbology (i.e., a specific type of barcode) that is widely used in the United States, Canada, the United Kingdom, Australia, New Zealand, and in other countries for tracking trade items in stores. Any product with an existing UPC does not have to be re-marked with an EAN. 2  In America the EAN adds 40% more codes, mainly by adding '10 through 13' to the '00 through 09' (0 through 9 in UPC) already in use. 3  This is a powerful incentive to phase out the UPC.
