- NAI defines Year 2000 compliance as the proper processing of date and date
- related data, including calculating, comparing, and sequencing. This
- includes the manipulation of this data with dates prior to, through, and
- beyond January 1, 2000, in a manner transparent to the user.
-
- This NAI product is a Year 2000 compliant version. In order to achieve
- this goal a formal test strategy had been developed and put in place to
- determine this compliance.
-
- The following details the items that we are looking for in the test plan
- and addressing if they are found. These items are not listed in priority
- order since failure to address any one of these could potentially be a
- problem for our customers.

- ***********************************************************************************
- Incorrect century recognition.
-
- Dates used as a special value:
- Special values of the last two digits in a year might be used for special
- purposes, for example 99, 365/99, or 12/31/99 might be used to indicate
- "no expiration date" or 00 to indicate an "unknown year".
-
- Incorrect field format determination:Some existing programs determine the
- date-time format (that is, MMDDYY, DDMMYY, and YYMMDD) by testing an
- appropriate part of the date field. For example, checking if the first
- two characters of the date field are values within an acceptable month,
- date, or year range (such as 1-12, 1-31, or ( 32).
-
- Sequence:
- When only two digits are used to represent a year, programs that collate
- year data will sort that data out of sequence in some cases. For example,
- the year 2000 (if represented as 00) will be ordered prior to the year
- 1999 (if represented as 99). Arithmetic calculations that operate on dates
- with 2-digit year representation might have potential exposures.
-
- Data integrity:
- In programs where historical dates are used, for example, all events
- occurring in 1800, 1900 and 2000 are not distinguishable when only 2
- digits represent the years.
-
- Leap year calculation:
- Note that the year 2000 is a leap year: A specific year is a leap year if
- it is either evenly divisible by 400 or evenly divisible by 4 and not
- evenly by 100. For example, the year 1900 was not a leap year but the
- year 2000 is a leap year.
