Each canner tends to use their own system of codes. Call the manufacturer to find out.
What ever the date on the can say's, or if no date about 1 year
Home canned goods can be safely kept until the lid starts to rust or the seal is broken, but really should be used before the next harvest. Commercially canned stuff usually carries a best-by date. I wouldn't use it much past 6 months later.
Canned tomatoes that have a dark color on top may be a sign of oxidation or spoilage, especially if there are signs of mold or an off smell. However, if the can is undamaged, and the contents smell and taste fine, they are likely safe to consume. Always check the expiration date and inspect for any other signs of spoilage. When in doubt, it's best to err on the side of caution and discard the can.

It would be the date the product was produced or canned.
There is no magic date. It will depend on the quality of the food to begin with, the quality and type of container and the subsequent handling and storage thereof. Even canned, food will degrade and change color, texture and flavor. I have used some items that were a year past the coded date. They were edible, but I could tell the difference when compared to newer product. Many canned foods are coded with 2 and even 3 year shelf lives. But for best quality and nutrition, plan to use canned goods within a year. If you are trying to maintain a cache of canned foods, use product throughout the year and replace it with fresh stock. Use the FIFO method - First In First Out. Always use the oldest items first.
You can use canned milk for up to one year after the use by date printed on the can. However, it may not be at its optimal flavor, or appearance.
Canned soda comes in regular and diet. The regular canned soda has about a nine month shelf life from the date it was made. Canned diet soda is good for about 3 to 4 months.
