Golden age question

[axisworks]

If you're in the midst of a golden age, and you happen to build the Taj Mahal, will the new golden age overlap the one you already have going, or will it start once the current age is finished?

If you get another golden age in the middle of one, the 8 turns are added on to the one you're in...

Note: Your 8 turns of extended golden age may vary, depending on game speed
(e.g., 16 turns at Marathon speed).
