The last WG14 meeting agreed, in principle, that a work item could
be started on new time facilities for C....
Where do we want to go from here ?
As seems clear from discussions on the tz mailing list, we need to
establish the scope of the new time facilities. This can include:
* Better time zone support (e.g. multiple time zones, a more
realistic model of daylight saving time)
* Better calendrical support (e.g. conversion to day numbers)
* Better support for realtime applications (e.g. benchmarking)
Only the first item is on-topic for the tz mailing list; perhaps
a new mailing list should be established for the C0x time API.
Here is is some current work in this area, which can be the start of
