Improve addition and subtraction Arithmetic Operators to handle time-related data types

We proposed to define the following valid operations: DateTimeOffset + DayTimeDuration -> DateTimeOffset DateTimeOffset - DayTimeDuration -> DateTimeOffset DayTimeDuration + DayTimeDuration -> DayTimeDuration DayTimeDuration - DayTimeDuration -> DayTimeDuration DateTimeOffset - DateTimeOffset -> DayTimeDuration Date + DayTimeDuration -> DateTimeOffset (or Date and throw away smaller components) Date - DayTimeDuration -> DateTimeOffset (or Date and throw away smaller components) Date - Date -> DayTimeDuration We observed that the following operations were valid, but did not propose adding them at this time: duration / int duration * int adjust (to change the timezone) Accepted: https://www.oasis-open.org/apps/org/workgroup/odata/download.php/47861/latest/odata-meeting-20_on-20130110-minutes.html
