Show Uptime in minutes and seconds, rather than just seconds?

[dusky beacon]

I'm pretty sure in the past my Dashboard showed Uptime sensors in minutes:seconds format, but recently I see it only in seconds.

Is there a way to change my Dashboard to show it in hh:mm:ss instead of just total seconds?

Change the unit_of_measurement to minutes, and it will show as minutes:seconds

or hours to get hours: minutes: seconds
