USGS press release on comparison of the M9.0 event of December, 2004, and the M8.7 in March, 2005.
Aftershocks during the first 24 hours indicate the extent of the rupture.

Initial findings from two US Geological Survey scientists, Dr. Bruce Jaffe and Dr. Robert Morton, who were members of a Sri Lanka International Tsunami Survey Team (ITST) that collected data to improve the understanding of the tsunami there
U.S. National Oceanic and Atmospheric Administration (NOAA) response to the tsunami.
From http://www.worldchanging.com/archives/001812.html : "Japan's National Institute of Advanced Industrial Science and Technology tsunami animation. Each frame is a ten-minute interval; the whole thing covers the first 180 minutes of the tsunami. It's a vivid demonstration of how long it takes for a tsunami to travel -- and why early warning systems can be so valuable."

Did the length of day change due to this event? Yes but the change may be undetectable.

I visited the Science Museum of Minnesota in October, 2004, an played with the settings on their wave tank. Even when I created a gentle slope of the "offshore" area, I didn't see an increase in wave height as the waves approached the shore. I wonder why?
