Uhhh, I have just remembered that there is another more precise
way (the one above might be 1-2 minutes off), if slightly more
involved; if one has a 'find' with the '-mmin' extensions one
probably also has 'touch' with the '-d' extension:

  STAMP="`tempfile`"; trap "rm -f '$STAMP'" 0
  touch -d 'last friday 17:37' "$STAMP"
  find "$DIR" -newer "$STAMP"
  rm -f "$STAMP"; trap 0
