The TTimeStamp encapsulates seconds and ns since EPOCH
This extends (and isolates) struct timespec
struct timespec
{
time_t tv_sec; /* seconds *
long tv_nsec; /* nanoseconds *
}
time_t seconds is relative to Jan 1, 1970 00:00:00 UTC
No accounting of leap seconds is made.
Due to ROOT/CINT limitations TTimeStamp does not explicitly
hold a timespec struct; attempting to do so means the Streamer
must be hand written. Instead we have chosen to simply contain
similar fields within the private area of this class.
NOTE: the use of time_t (and its default implementation as a 32 int)
implies overflow conditions occurs somewhere around
Jan 18, 19:14:07, 2038.
If this experiment is still going when it becomes significant
someone will have to deal with it.
This class is also known as (typedefs to this class)
timespec_t
