Cisco Systems' Year 2000 Compliance Definition

• More Information on Year 2000 Compliance

Definitions

Software Products shall mean any level of software including, but not limited to, microcode, firmware, operating systems, application programs, files and databases which may be provided by Cisco.

Four Digit Year Format shall mean the format which represents all four digits of the calendar year. The first two digits represent the century and the last two digits represent the year within the century (e.g. "1996" is represented as "1996").

Leap Year shall mean the year during which an extra day is added in February. Leap Year occurs in all years divisible by 400 or evenly divisible by 4 and not evenly divisible by 100. For example, 1996 is a Leap Year since it is divisible by 4 an d not evenly divisible by 100. The year 2000 is a Leap Year since it is divisible by 400.

Year 2000 Compliant shall mean all calendar year representations used within the Software Products which, when operated (including, but not limited to, arithmetic, comparison and sorting operations) before, during and after the actual calendar y ear 2000 A.D. shall not produce subsequent operations and/or generate output which yield results in variance with the normal course of operations of the Software Product or error conditions which are the direct result of the use of a calendar year represe ntation. Software Products will process calendar dates (including, but not limited to, arithmetic, comparison and sorting) using a Four Digit Year Format. Software Products will correctly process calendar dates for Leap Year. Data which is processed by Ye ar 2000 Compliant Software Products will be compatible between Software Products which are not Year 2000 Compliant. In addition, the Year 2000 Compliant Software Product shall continue to be in compliance with the Software Product's specification and will continue to perform its functionalities before, during and after the year 2000 provided Software Product is under Cisco's then-current standard warranty or under a maintenance agreement with Cisco or with a Cisco authorized service provider or reseller.

Accordingly, Cisco's Year 2000 Compliant Product shall do the following:

• General Integrity - Products/services will accurately process date/time calculations (including, but not limited to, calculating, comparing, and sequencing) from, into and between the twentieth and twenty-first centuries, between the years 1 999 and 2000, and during a Leap Year.
  

• Date Integrity - All manipulations of time-related data (dates, duration, days of week, etc.) will produce desired results for all valid date values within the application domain.
  

• Explicit Century - Date elements in interfaces and data storage permit specifying century to eliminate date ambiguity.
  

• Implicit Century - For any date element represented without century, the correct century is unambiguous for all manipulations involving that element.
  

• Interfacing - Year 2000 Compliant Software Products, when used in combination with other year 2000 compliant products, shall accurately process date/time provided that such other products properly exchange date/time data with it.
