YEAR 2000 COMPLIANCE NOTE
Important Note :
All systems with which Teknor products interface and/or the data that they receive must be
themselves year 2000 (Y2K) compliant. Equally as well, any customer using a Teknor Y2K
compliant product may experience problems with operating system and/or application
software that do not correctly read the date (you should consult Teknor Y2K website
information page and obtain the specific product Y2K compliance letter to confirm product
compliance).
Even if the Operating system is Y2K compatible, application programs that use time
and date may not properly handle or use the century data, and this can lead to
failures in a system that is otherwise Y2K compatible .
This date recognition problem does not result from any fault of the hardware, but from how
the Time and Date are accessed or handled by the software. If the software reads the RTC
directly, it could fail as the transition occurs, because the BIOS or Operating System has not
had a chance to update the century byte.
All programs should use either the appropriate OS calls or BIOS interrupt functions to
access time and date information.
Programs must also properly utilise all of the data that is returned, as the BIOS or Operating
system could return the proper century data, but if the application ignores this data, a failure
could result.
The customer should check with its operating system and/or application software vendor(s)
to determine what, if any, Y2K issues their installed software could have. If possible, the
customer should consider performing tests to verify proper Y2K operation prior to December
31, 1999. If testing is to be performed, ensure that the test system is configured exactly like
the systems in question.
Remember to test the OS, hardware, and all applications that are or will be installed
on the system .
There is no way for Teknor to determine or predict the choice of operating systems, system
software, or applications our customers will make. Teknor claims no legal responsibility for
problems that may result from action or inaction taken regarding this information. Teknor
provides this information as a service to our customers, knowing that software problems
might result if this issue is not properly understood and addressed. Teknor strongly
encourages all customers to investigate this matter fully.
