We have experienced issues on some machines where when opening certain screens within the system users are being presented with an error message.


This error is caused by incompatible date format settings currently set within Windows. as ClockOn uses the Windows region settings within to determine how the date format is displayed within the system.


The guide below will show you how to fix this issue.


  1. The first step is to open the Control Panel, to do this click the start menu and then type Control Panel into the search box, this will show the Control Panel app.

  2. Once this has been opened you will see the Adjust your computer settings screen. select the option to  Change date, time or number formats.


  3. This will open the Region screen

  4. From here you will need to change the Format drop-down to another settings for example "English (Canada)" then click the Apply button to accept the change.


  5. Change the above setting back to English (Australia) and click the OK option to save and close the screen.


If the above does not solve the issue you can try the following steps

  1. Re-open the Region and Language screen as per steps 1 to 3 from the previous guide, then click the Additional Settings button.

  2. Select the Date tab and ensure that the Short Date field is separated using the  /  symbol.
            Correct dd/MM/yyyy           Incorrect dd-MM-yyyy      


Once this has been modified you should now be able to use the ClockOn application without receiving this error message.
