Listing agents are responsible for changing the information on MLS. The best and fastest way to learn is asking to the listing Agent directly.
When you access MLS information via many websites that use IDX (our method of direct access between a Realtor website and the MLS database), the data will be realtime. Updates are instantaneous. Some websites use other methods to update the material found on their websites and may not completely update listing status or pictures for days.
So, if the Realtor inputs the CON status as you read this, IDX-connected sites will reflect that as soon as you check it after reading this. If she waits 5 days and you check it on some other websites, you may not see the change until next week.
Have a blessed day!

As for the information updating from the MLS to Trulia I am unsure. Someone on the staff of Trulia would be more informed on this part.
It is very possible that Trulia does not update the status very often evident from all the questions about status of properties and the response from agents that properties are already sold.
From your question I assume "Congradulations" are in order.
