shuttle entry viewing times

Is anybody else curious about the choice of 1000 for the time of the
deorbit burn? The prelaunch time for deorbit was 1007, the most recent
version of the nasa tv schecule I've seen (E) gives 1015. The times
look a little early based on the current planned landing time (same
source) of 1112.

A way to check would be to get the time of the orbital pass for San
Fransisco from a fresh TLE and compare it to the time given in the table
to get an offset for any locations of interest. Unfortunately I don't have
a tracking program for the platform I'm on right now so I can't check.
