Here is a copy of my current configuration for T-Clock in the system tray.
Can anyone explain (write out) the correct configuration to have the two lines reversed; i.e., have the time on top and the date on the bottom?
The application was released back in 2010 on the DonationCoder forum. The status of the project is now listed as closed and the author didn't continue the development. I believe that the feature you've mentioned above has to be modified by the developer himself because this is the way the software has been designed.
I recommend to post on that Forum, maybe the developer watches the thread. Access the forum using the link posted below.
