    typedef struct {
      char bSeconds;
      char bMinutes;
      char bHours;
      char bDay;
      char bMonth;
        char bYear;
        union {
        char bFiller1;
        struct {
          unsigned char fTimeIsUTC: 1;
          unsigned char fUnused: 7;
        };
      };
      union {
        char bFiller2;
        struct {
          unsigned char fOSSnapshot  :1;
          unsigned char fReserved  :7;
        };
      };
    } JET_BKLOGTIME;
