I copied the tsUtil library in /adaqfs/home/a-onl/vme/tsUtil and loaded the library.
One can get the deadtime by typing ( from README.tsUtil )
int tsLive(int sflag);
Return TS Live time as an integer 0-1000 where for example 995 -> 99.5% live sflag = 0 return differential livetime (since last call) 1 return total integrated livetime
void tsLiveClear();
Clear live time scalers
