I started testing the display of seconds on the clock. Now, I can't get rid of it. I have tried, unsuccessfully to update these settings in Preferences and Preview still reads the time in seconds. I have not tested this on the actual BrightSign unit as it is being used in our public space at this time.
In Preferences, my current settings are %l:%M and it shows the Time as 9:23 AM. This looks correct, however, when I Preview the presentation the seconds continue to display. I have tried starting with a new project and also updating an existing project. Same thing, the seconds still display.
