Review Comment:
   Please specify guaranties of the method in the contract. It's not clear 
whether the method will return true if logical timeout was exceeded or if it 
was detected, etc? In other words if transactions with timeout 20 was started 
at HLC timestamp t(10,10) will isTimeoutExceeded return true if HLC(t30, X)?
