About the Py_BUILD_CORE issue:

You are suggesting that I define this in datetimemodule.c
just prior to the include of datetime.h? Or are you
suggesting some other macro? I am not sure about the comment
about "not needing a macro in the first place" since there
are two groups that will be importing datetime.h: the first
being the datetime module itself and the second being the DB
API modules. The macro is definitely required to distinguish
between the two -- unless I am missing something?

On the TimeFromTicks() issue:

You obviously consider it important that the three methods
be available at the C level for DB API module authors to use
directly. My objection is simply a reiteration of an
objection raised by Tim Peters. I think you'll have to argue
that one with him. :-) I'll provide my implementations for
cx_Oracle as part of the patches and then you can fight it
out and I'll stay out of it. :-)

As for the transition period, I assumed that with the
introduction of a standard datetime module, that it would
become the suggested implementation for database interfaace
modules. That said, I don't really have any authority to say
anything on this front so I'll leave that to you and others
to decide. :-)
