I found this article which has an excellent summary of the Conclave process and estimated times for those of us in the US.
Here are some highlights:
*]The first smoke signal can be expected about 7 p.m. [2 pm ET] Tuesday, after the first vote.
*]Beginning Wednesday, smoke would be expected at about noon [7 am ET] and again about 7 p.m [2 pm ET].
*]However, if a pope is elected on the first ballot of the morning, the white smoke would billow forth between 10:30 a.m. and 11 a.m. [5:30 am and 6 am ET]. If he is elected on the first ballot of the afternoon, the white smoke would be seen between 5:30 p.m. and 6 p.m. [12:30 pm and 1 pm ET].
*]After a white smoke signal, it takes about 40-45 minutes before the announcement of the name of the candidate who won. He must accept the office, change to white vestments and the cardinals pledge their obedience and pray again.
