In the military Julian Date system the first number is the last digit of the year and the following three digits are the day of the year. The system works well with one exception. In this case the 1 could represent 1991, 2001, or 2011. Nasa and the rest of the world use the Julian calendar whose first 2 digits are the last digits of the Gregorian Calendar year to avoid this issue. So your trans was probably rebuilt on November 14, 2011.
