"2100" (wrong century) Display Problem Cures

There are several possible causes for incorrect display of the year after the transition from 1999 to 2000. In order to resolve the problem as quickly as possible, the possible causes should be explored in the order presented below:

A significant number of otherwise-compliant computers exhibit a century 'rollover' problem.

This problem causes the CMOS clock to return a different date than the on-board clock. Any program which runs on such a machine may retrieve two different dates depending upon the exact method used to query the system.

To the user, the incorrect date may appear as '2100', '2099', '2049', or '1980'.

This condition has been observed on a wide variety of brands, board designs, and processor types. This problem can be corrected on the vast majority of these computers via the following procedure. Once corrected, the clock will continue to function properly without further operator intervention.

  1. 'Hard boot' the computer (via power off/on or RESET).
  2. While the computer is performing its power-on self-test, hit the DELETE key to get into the CMOS setup screen.
  3. Enter the STANDARD SETTINGS area of the CMOS setup. Check the DATE display. If the year does not display correctly, correct it. On many systems, the CMOS initialization process initiated by examining the date will correct the display without any operator intervention.
  4. When the correct date is set, exit the STANDARD SETTINGS area of the CMOS setup. Regardless of whether operator action was necessary to correct the date, select SAVE SETTINGS AND EXIT (rather than EXIT WITHOUT SAVING) to correct the date permanently.
  5. Boot the computer normally and retest.

WARNING: DO NOT CHANGE ANY OTHER SETTINGS IN YOUR CMOS!!! If you accidently make a change in some other value, either EXIT WITHOUT SAVING or hit the RESET button and try again. If you are not sure, hit RESET and try again. If you are uncomfortable with this procedure, obtain professional hardware assistance.


Check your hardware per the procedure above first: you cannot cure hardware problems with software changes.

If you are running WIN 95/98, right click the time or clock display on the desktop. Make sure the clock is set to 4-digit year mode. If you change this setting, restart Windows. If WINDOWS 95/98 is on your machine, you should correct this setting: even if you choose to start Payroll from DOS.

If you have made any changes in hardware or Windows settings, examine the current period date using DATASMITH Payroll's "Change Date" function (IN-CD). If the Change Date function corrects the current period date, you have successfully completed the correction.

If DATASMITH Payroll's "Change Date" function does not correct the current period date, and if you have checked the HARDWARE and Windows settings (if applicable), you should make sure you have the latest version of the payroll modules installed. Check the web site:


Choose "Client Support" on the home page. On the Client Support page, select the module you wish to update. Enter your Client ID (usually your primary phone number) and your password to activate the download facility. Follow the update directions appearing on the screen. You can use your web browser to print these directions for future reference.

As always, make sure you have a backup copy of all programs and/or a complete set of Master Disks before updating.

If your current-version Master Disks are lost or damaged, you can obtain a complete updated duplicate set from LPI for $39.

When downloading updates for date problems, we recommend that you download the INITIALIZE and Utilities module first. If the updated INITIALIZE and Utilities module immediately allows you to display and change the current period date using IN-CD, you have confirmed that updated modules are what you need. Download updates as needed for any other Main Menu selection which does not display and/or accept dates properly.

WARNING: If you have DATASMITH Custom Payroll or DATASMITH Professional Payroll, DO NOT download modules from the web site: those modules are for STANDARD CONFIGURATION payroll systems only and may disable your custom features! If a new module refuses to run and displays a message such as "WRONG MASTER VERSION...", you cannot use the STANDARD CONFIGURATION updates: restore your previous version programs and contact LPI Information Systems for update assistance. The "WRONG MASTER" message comes from the Version Interlock feature which is designed to protect your data files from use of incorrect program module versions.
