Examine the date codes on the packaging labels of inventoried parts that are listed in Table 1.A date code is printed with "D" for the day, "M" for the month, and "Y" for the year. The day, month, and year are represented by two-digit numbers.The date code of "D01M03Y12" is for 1March 2012.Any package with a date code that precedes "D01M03Y12" is suspect.Inspect the contents of packages with a date code that precedes "D01M03Y12".
