No, but we 'Murricuns aren't much given to having others tell us what to 
do; note the similar reluctance for widespread adoption of metric for 
common use; after nearly 40 yr since was a widespread attempt to 
enforce, it's still gotten essentially nowhere outside industrial and 
scientific circles and I suspect another 40 will be about the same.

Date convention in US is a similarly ingrown habit; that there are 
coding standards is pretty-much immaterial to the casual user and I'd 
venture 70-80% of the spreadsheets in use are done by just that type of 
individual; may be pretty adept at the usage of Excel interface and all, 
but little or no actual coding training so they continue to just use 
everyday convention.

As noted  in an earlier response, in a 40-yr+/- consulting career in 
mostly data acq and instrumentation for power utilities I saw a hundred 
or more data acq systems put together from probably over half that many 
vendors and every conceivable form and some that were truly incredible 
for encoding date and time was in the sample set I think.  As noted, 
even vendors would (and I'm sure still do) provide sample code most 
probably put together by the summer intern that would think something as 
sophisticated of deliberately using the sequence order of d/m/y as 
almost revolutionary and, probably, "European".  Teaching those folks 
about serial numbers is a struggle that one rarely wins.

As noted, Matlab has a class |datetime| and has enhanced the C i/o 
format string to read date strings such that one can on a case-by-case 
basis handle it on input.  MS tends to also be heavy-handed in they code 
as if everything is MS-consistent and leave it up to the user to conform 
or write the glue to interact.
