You can mod by yourself

Are you talking about this?

There is already a "seconds" unit, so we can add units like "hours", "days" etc. But to achieve formatting like "01:12" (I guess) we will have to also add "special" units like "time" and "date_time" or something like that.

For example, if placeholder var has a value of 1 hour 25 minutes, then

Formatting string	Result
"{var*h}"	1.42h
"{var*m}"	85m
"{var*s}"	5100s
"{var*time}"	01:25
