   The following definition is in common for 32 and 64 bit machines.
   In both architectures, the field must be loaded into a time_t

   #include <time.h>

   time_t t;

   t = eventHeaderStruct.eventTimestampSec;
   cTime( &t ); (or whatever else can be done with a time_t)

   Please note that the available timestamp will wrap sometime
   around Jan 18, 19:14:07, 2038...
