I tried that in early version of mxDateTime -- it fails
badly. I switched to the local time assumption very
early in the development.

Note that Fredrik's type is an abstract type; it doesn't
even store anything -- that's up to subtypes which of
course can implement timezones at their liking.

The type will store a fixed point in time, so why
worry about leap seconds (most system's don't support these
anyway and if they do, the support is usually switched off per
default) ?

In the abstract base type ?
