11.4: Date/Time Conclusion

Each embedded system could be impacted by a variety of date/time representation issues. Even whether a particular date/time representation issue impacts a system is questionable. A system using only the RTEMS Classic API is not impacted by the date/time representation issues in POSIX. A system not using date/time at all is not impacted by any of these issues. Also the planned end of life for a system may make these issues moot.

The following is a timeline of the date/time representation issues presented in this section:

2000 - Two BCD Digit Real-Time Clock Rollover
2038 - POSIX time_t Rollover
2088 - Correction for Two BCD Digit Real-Time Clock Rollover
2099 - Ada95 Ada.Calendar Rollover
2124 - RTEMS Internal Seconds Counter Rollover
