{"abstract":[{"text":"The  most  natural,  compositional,  way  of  modeling  real-time  systems  uses  a  dense domain  for  time.  The  satisfiability  of  timing  constraints  that  are  capable  of  expressing  punctuality in  this  model,  however,  is  known  to  be  undecidable.  We  introduce  a  temporal  language  that  can constrain  the  time  difference  between  events  only  with  finite,  yet  arbitrary,  precision  and  show  the resulting  logic  to  be  EXPSPACE-complete.  This  result  allows  us  to  develop  an  algorithm  for  the verification  of  timing  properties  of  real-time  systems  with  a  dense  semantics.","lang":"eng"}],"scopus_import":"1","date_published":"1991-01-01T00:00:00Z","acknowledgement":"We  wish  to  thank  an  anonymous  referee  for  pointing  out the  PSPACE-fragment  of  Section  4.5.
