I don't think this merits a new core type.
I would add it to the metadata as an array of two unsigned ints, which is how
it's encoded in Imf::TimeCode. You'd want something like this in exrinput.cpp:
static TypeDesc TwoUints (TypeDesc::UINT, 2);
Imf::TimeCode tc = ...; // get the timecode from the EXR file
spec.attribute ("openexr:TimeCode", TwoUints, &tc);
And then to extract it (including in exroutput.cpp):
ImageIOParameter *f = spec.find_attribute ("openexr:TimeCode",
TwoUints);
if (f) {
Imf::TimeCode tc = *(const ImfTimeCode *) f->data();
... do your thing with tc ...
}
