How can I show the current time in VTScada Idea studio in 24 hours & 12 hours format?

1. Use the big A in the Idea Studio Ribbon to add a text box.
2. Right-click to open Text Properties.
3. Open the expression editor in the top right corner (Blue and white box).
4. Enter this function and close the dialog and close the Idea Studio.

Time( Now(2), 2)

Make a new text box and use this function.

Time( Now(2), 7)
