prismatic/timeless hourglass

I just returned to the game a few weeks ago. In trying to join in some endgame content, dynamis. I tried to get the new required hourglass, prismatic. The npc that supplies it asked me to trade the old timeless hourglass to it in exchange for the new one and 500k G. But nowhere in my inventories do I carry a timeless hourglass. I have done dynamis before, but I dont have that item, at least anymore. I cannot continue the content with out the item.

The dialog will not continue to the point of purchase, without the traded item. I also cannot figure out how to make a GM call in game. I have no options available that "Call GM". Just articles that might help you.
