With that in mind I am going to suggest that a new interface is made available in addition to those in the existing implementation

mama_status

mamaDateTime_setFromStructTimeSpec(const mamaDateTime dateTime,

                                   struct timespec*   inputTimeVal);

mama_status

mamaDateTime_getStructTimeSpec(const mamaDateTime dateTime,

                               struct timespec*   result);

They're pretty much identical to the existing timeval based functions but with timespec instead and their implementation should very very straightforward based on what's already there so in terms of code it's a small change.

An explicit definition of timespec can then be defined in port.h for versions of MSVC which don't define it. It'll also mean that we effectively add support in the interface for nanosecond support in case anyone wants to support that too.

Raising it with the list to make everyone aware because these new functions should be the preferred methods for payload bridge developers to use if they want to support extended ranges properly on both windows and linux.
