Format time from 0:00:00 to -:--:-- for washer

I’m utilizing this custom card, GitHub - phrz/lg-washer-dryer-card: Lovelace cards for use with the Home Assistant LG ThinQ Integration, which I love, but would like to change it slightly. When the unit is washing, the icons and time change brilliantly. However, once the machine is done with the cycle, the static display reads as below:

I’d like to change the “resting” display to dashes indicating the unit is basically off.

Not sure if this should be some sort of templating, helper, or what.

Appreciate any advice.

That’s something you need to bring up with the custom card developer.

Thanks @tom_l , I’ve reached out to him several ways but no response.I can wait and see.
