[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

Ralf Handl updated ODATA-71:
----------------------------

    Proposal: 
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)

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)

>          Issue Type: Improvement

>    Affects Versions: WD01
>         Environment: [Proposed]

>  In section "5.1.1.2.1 Addition Operator" and "5.1.1.2.2 Subtraction Operator" the operators add and sub are defined on numeric operands only
>  For some use cases  the addition or subraction of time-related datatypes would be very valuable.
