Tag formatting in FactoryTalk View

Okay so the situation is as follows. I have FactoryTalk View 7 installed and running my SCADA at one of our locations now. I have a Daniels gas chromatagraph running at the location and I am not only pulling the gas percentages from it but also a time of last run output. Currently this output displays in the format HHMMSS to show the time of the last sample in 24 hour time format, I would like to format this output on the screen to show as HH:MM:SS. Does anyone know if there is a way to do this?

Is this running FT View ME or SE?

What data format is the tag? Is it being read from a PLC or is it an internal system tag from FT View?

Its running SE. The tag is read as a numeric output and is coming from a Red Lion device from Modbus.
