My co-worker's father works at NASA and e-mailed us this info;

'MARS PHOENIX LANDER' TIMELINE times Central
NOTE: Navigational adjustments before Sunday could shift times by up to ~ 30 seconds. Mars event times are listed in "Earth-receive time" (ERT) rather than "spacecraft event time" (SCET). This means the listed time incorporates the interval for radio signals traveling at the speed of light to reach Earth from Mars. On Sunday the two planets are 171 million miles apart (275 million kilometers), which means it takes the signal 15 minutes and 20 seconds to reach Earth. For some spacecraft events, engineers will not receive immediate radio confirmation.
