/*

       Vmstime.h  v1.6A

       Author: Paul Nankervis

       Please send bug reports to Paulnank@au1.ibm.com

        1.4A Changed default DOLLAR handling to include DOLLAR
             identifers unless NO_DOLLAR is defined
             (ie #ifdef DOLLAR to #ifndef NO_DOLLAR)
        1.5  Moved more header info here and added cvt_internal support
        1.6A Fixed endian problems in addx/subx
