Accumulated Time format in Totalizer with timetrue option

Hi  all,

I have created a totalizer as:

Counts Event, setting Time when True, block and equal to 1.

My goal is to count how long a signal is set to 1 and with this configuration the totalizer is working properly counting how many seconds the signal value is 1.

But I need to display  the result in relative time with this format hh:dd:ss instead of only ss. I tried changing Totalizer Point Type to Timestamp but the result is shown in absolut time from 01/01/1970 01:00.

How can I get to express, for instance, 5400 like 1:30:00 using Totalizers?

Thank you in advance.
