[Pharo-users] Formatted print for Duration

Hello, I do not see how to do a formatted print from a duration. I would like to be able to do something like: String streamContents: [ :s | 90 minutes formatted: ‘hh:mm’ printOn: s ] The Duration>>#printOn: method prints the ANSI 5.8.2.16 format: [-]D:HH:MM:SS[.S] The Duration>>#printHumanReadableOn: is not printing in the format I want. Am I missing something or such feature does not exist actually?
