I asked this question in the Centera Support community. Looks like I should have asked it here in Developer Network > Centera, so...
Per SDK API Programming Guide, page 247-248, Reflections have 'creation.date' plus all the C-Clips standard attributes, including the deleted C-Clip's 'creation.date'. When I use FPQueryResult_GetField() to get 'creation.date', I get the reflections 'creation.date'. I also get the reflections 'creation.date' if I ask for it a second time or if I use FPQueryResult_GetTimestamp().
How do I retrieve the deleted C-Clip's 'creation.date'?
Don't know if it matters, but I am using SDK 3.1.544 (running Win2003 server).
