Logged In: YES user_id=619560 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. :-)
