    Lest the wrong impression of US legislation pertains: the _currrent_
    version of 15 U.S.C. 261 of 2007 reads in part:

       " standard time of the first zone shall be Coordinated Universal
         Time retarded by 4 hours; ..."

    so the term "standard time" is defined as it used by tzdb,
    and no "antemeridian" is referenced. Current law references UTC:

       " the term ‘Coordinated Universal Time’ means the time scale
         maintained through the General Conference of Weights and Measures
         and interpreted or modified for the United States by the Secretary
         of Commerce in coordination with the Secretary of the Navy. "

     See eg
