Also, your interpretation of #- as "to" would break with the existing "minus" in DateAndTime. :-)
If you want to add such an interface in your source code, I would suggest something like #--> to make the intention more clear. However, it is not of much use in the Chronology package in general. I think.
Best,
Marcel

Yes. Conceptually, it does not make sense because class Time does not
represent a magnitude. If you want to think of the time of day as a
magnitude, then class DateAndTime is probably what you want.
The class comment for Time explains:
If you need a point in time on a particular day, use DateAndTime.
If you need a duration of time, use Duration.
