Sorry, but that's incorrect. "ESuT" is commonly
used by the Australian Transport Safety Bureau.
My apologies; that comment was based simply on the strikingly low number of results from a couple quick Google searches. (I admit I didn't really look at the results themselves, as I now see that some ATSB reports using "ESuT" do appear around position #5 for that term in the .au domain.)
That said, I actually ran searches on Altavista and Google much like your October 2012 survey, and all of the result counts for "(A)xSuT" on .au sites were at least two full orders of magnitude lower than the corresponding "(A)xDT" abbreviations, in some cases up to four. Strike "no documented use" from my earlier comment and replace it with "little documented use".
Further, even the ATSB isn't entirely consistent on their usage. It didn't take much searching to find several accident reports where the time of an incident is given under General Details in "xDT"... not "xSuT" as would be expected:
