Seeing that the turn-founded stored by the DLL can't be modified through Python, hardcoding the dates in
Assets\Python\Screens\CvReligionScreen.py may indeed be your best bet. I think this is the loop you'd have to modify:
Code:
xLoop = self.X_RELIGION_START
for iRel in self.RELIGIONS:
if (gc.getGame().getReligionGameTurnFounded(iRel) >= 0):
szFounded = CyGameTextMgr().getTimeStr(gc.getGame().getReligionGameTurnFounded(iRel), False)
screen.setLabelAt("", szArea, szFounded, CvUtil.FONT_CENTER_JUSTIFY,
xLoop, self.Y_FOUNDED, self.DZ, FontTypes.SMALL_FONT, WidgetTypes.WIDGET_GENERAL, -1, -1)
xLoop += self.DX_RELIGION
Not all that easy to implement. The self.RELIGIONS list (which doesn't exist in Vanilla Civ 4, it's an AND thing) may contain the ids of all religions or only of those already founded, depending on an option on the BUG menu. The ids correspond to the order of
XML\GameInfo\Civ4ReligionInfos.xml, starting at 0. getTimeStr expects a turn number, but I guess it would be more convenient to provide a year number. Unfortunately, no utility function for converting past years to turn numbers seems to exist. You could simply enter year strings ("AD 50" or so), but then you don't have translations. If you do use game turn numbers, you'll get different years for different game speed settings.
