  The annoying workaround is to do $duration->days * 24 + $duration->minutes or something similar. I'd rather it gave me that automatically and warned about any potential consequences, either that or worked it out correctly. Also it's called DateTime::Duration not interval iirc

  Hello,
  
  You might want to consider something along these lines.

  There's a module called DateTime::Format::Duration that should do what you want. Unfortunately, it needs some work to pass its tests with the latest DateTime.pm.

    The last time I checked (this morning), it did not do what I wanted. It could tell me the minutes component of the interval, but it could not convert the days, hours, and minutes to a total number of minutes. Unless I'm missing something, and if so, please point it out, because you will really help me.

        Yes, I did, and thank you! I'd discovered delta_ms by that time. However, it still does not really DWIM. If I have real Date objects, I should be able to subtract them and get an interval that can be converted to whatever resolution or units I want. The problem then is that I have to do something unintuitive with my DateTimes: intuitively, I had written

        $end - $start

        and expected to get something that I could express as minutes. I shouldn't have to perform something other than subtraction in order to

      I think you'd be best served by writing a message to datetime@perl.org outlining what you want to do.
