The Time\Duration class will also implement internal “comparison handlers”, which means that direct comparisons with operators such as < will work. While reading this I asked myself why we need a specific Duration class...

What is the difference between new Time(12, 23, 34.567890); and new Duration::fromIso8601String('PT12H23M34.567890S'); Both define a number of hours, minutes etc. The only "difference" is that we came to see a time as starting from a certain point in time. But that is in essence just a convention and the time component of a DateTime just represents the a duration. Also the "limitation" to 24 hours is a convention (that gets blown away in DST situations. As do the 59 seconds with leapseconds) If we want to think about an improved way of handling datetimes, why not introduce a Time-class that can later be used in combination with a Date class and a Timezone class to define a point in time (or without the Timezone to define a local DateTime). After all we can already add more than 24 hours to a DateTimeInterface via setTime (see https://3v4l.org/QZnZ2#v) - so there should be no issue with creating Time-objects with more than 24 hours... Don't get me wrong! I like the idea of a dedicated class that holds a Time-based duration. I just think we do not need a separate "Duration" and later a "Time" class when they both - in essence - hold the same information.
