Well, your link went nowhere, but I checked and the T-P does say it was late Monday morning. The 3 a.m. timeline I got from a post here a week or so back that quoted Knight-Ritter reporting about a National Guard Timeline stating 3 a.m. Here is a link to the Knight-Ritter article:

The late Monday morning timeframe does seem to make more sense.
