Created attachment 30352 [details] Patch for function Dec2Oct + testcases Patch for function Dec2Oct + testcases
This seems to be incomplete as the new function is not registered anywhere? Also similar functions implement FreeRefFunction, but this one not, any reason why?
This patch is outdated, a new patch will be attached soon
I am closing this for now as we never got an updated patch, please reopen this bug if you manage to create a complete patch against the current version of POI.
