Put the summary of the bug you're having here

What I expected to happen was...:
The clock trade in their trading GUI would not show the actual time.

What actually happened was...:
The clock in their GUI showed the correct time of day in Minecraft. This bug is similar to the one where the time shows up in the crafting book.

Steps to Reproduce:
1. Put a step by step guide on how to trigger the bug here:
2. Get a villager.
3. Make the villager have the librarian profession.

4. Level that librarian up to the level of expert or above.

5. Examine the clock trade he may have. If he does not have the clock trade, repeat steps 2-4 until he does.
