CONVERSATION TIMER SHOW

I have created conversation timer:

DECLARE @DialogHandle UNIQUEIDENTIFIER;

BEGIN dialog CONVERSATION @DialogHandle 
FROM SERVICE myService
TO SERVICE  'myService'
ON CONTRACT [DEFAULT]
WITH ENCRYPTION = OFF;

BEGIN CONVERSATION TIMER (@DialogHandle) TIMEOUT = 7200;

That means that after 2 hours message will be delivered into my queue.
Where can I see which timers are active and when they will deliver the messages.

I can see the timers here:

SELECT * FROM sys.conversation_endpoints WHERE far_service='myService'

But there is no data about when this endpoint was started nor when timer will timeout and deliver the message.
Here is only dialog_timer date and lifetime date which are some different values.

thanks,

Simon
