How bosses time works when worlds are merged?

Question

I have a character that is on a recent merged  world, and I want to know how the bosses time (bosses like Shlorg, Yeti, Zushuka etc) works when the worlds are merged. They start from zero? They start with high chance? How to start checking?

Answer 1

All times get a reset and start from zero, others bosses like Ferumbras (Every 6 months) starts from the beginning. Or Dharalion (Every 6-8 days) he gonna appear in that time 6-8 days from the start of the server.

I think I know what you meant but your answer is a bit confusing. You say that "all get reset" but then you go on to give examples as if Ferumbras and Dharalion behaved differently. Can you clarify your answer, please?
