Regarding (a), section 4.4.4.3 in https://www.loc.gov/standards/datetime/iso-tc154-wg5_n0038_iso_wd_8601-1_2016-02-16.pdf represents a time interval by start and duration. This implies an arithmetic operation to determine the end, e.g., in 20190227/P1M2D (the example in b).

Hi,

 

I did some more research around ODATA-1394

 

 

a)  I was not able to find anything that states that ISO 8601 talks about the arithmetic operations for durations or any other type.

I can not guarantee that they donât since the ISO standard requires a license and I do not have access to a licensed version but I couldnât find any indication that it does.

 

b) I had to double check it myself and can now confidently confirm what you, Ralf brought up .
When adding 1 month and 2 days to 2019-02-27

         Month first leads to 2019-03-29    (2019-02-27 -> 2019-03-27 -> 2019-02-29 )

         Days first leads  to 2019-04-01    (2019-02-27 -> 2019-03-01 -> 2019-04-01 )
