Just thinking that the clock may have misread the military time on the Pacific International Dateline as 05:37:19 Spetember 12 so it comes out as military time (17:37:19 September 12)
fyi, I am aware of no military (or other) use of "International Dateline Time". Most military time is either local, or Greenwich Mean Time (also known as Zulu).
Also, at the moment of impact (0937 local, 1437 Z), it would have been 0237 on the 12th, in the Pacific.
