The date stamped is the best used by date.
How do you read the code date? The first 2 numbers are the month, the next 2 are the day, and the last 2 are the year. The last digit (after the space) is a production number.
Example: If you see a “use by” date of 050916 4, the use by date is May 9, 2016.
Our newer dating system for many of our products has the time of day after the date.
Example: If you see a “use by” date of 050916 13:21, the use by means May 9, 2016 1:21PM;
the time of day is when production produced the product
