Format of text in ignition reporting

Dear All
I would like to ask about the reporting, I have report like this

At the bottom you can see stop times and i want them in the format hh:mm:ss

datasource for the int_stoptime is tag history

In the perspective i used

dateFormat(addSeconds(midnight(now()),{int_StopTime}),"HH:mm:ss")

Can you please help me how can i configure expression on the text like these in reporting?

Thank you very much
