Error description

• The F <server>,DISPLAY,THREADS,AGE=xx command was used to
  display information about the requests, for which the amount of
  time that has elapsed since the request was placed in dispatch
  is equal to or greater than the specified amount of time.
  However, the new threads (less than the specified amount of
  time) were also reported in the result which was incorrect.
  For example:
  12.28.45 STC12154  BBOJ0111I:  REQUEST   ASID JW TO RE DISPATCH

  The problem was determined to occur when ras_time_local=1 was
  set in the server environment.
  

Problem conclusion

• Code which checks the age of a thread has been updated to
  remain accurate when ras_time_local is enabled.
