Mars Orbiter Mission arrival timeline

Edit Sep 21: Some of the times in the Pacific Time column were not correct when this was originally posted. I have fixed the error. Sorry and thanks to Sameer for pointing out the error in the comments.

Mars Orbiter Mission's fated arrival day is approaching fast! ISRO released a timeline of the critical orbit insertion events yesterday, and I thought it would be handy to people for me to convert this to some other time zones. Also, one item in the ISRO timeline made it clear that all of the times they are mentioning in public communication are spacecraft event time -- that is, the time on the spacecraft's clock when the events take place. But we on Earth will be 224 million kilometers from Mars on that day, and it will take 12.5 minutes for the signals from the spacecraft to reach Earth. So I have also added those 12.5 minutes to the times listed below, making them Earth Received Time. These are the times on our clocks when we will hear from the spacecraft...or not. If these times change at all, I will update this blog entry with new information.
