Error description

• 'cleartool space -update' hangs on the Daylight Savings Time
  transition day
  
  
  ClearCase 7.1.2.x
  
  
  Solaris 10 x86
  
  
  
  Problem as Investigated:
  
  On November 7th, 2010 at 2:00 A.M., Daylight Savings Time was
  over and the system clock was automatically turned back an hour.
   Thus, what was once 2:00 A.M. was now 1:00 A.M.   As well,
  there had been a scheduled job within the ClearCase scheduler
  that prior day which was run at approximately 3:31 A.M. in the
  morning and finally completed at 3:31 P.M. on the very same day:
   The Daylight Savings Time was some twelve and one half hours
  later, the following day.
  
  On the Daylight Savings Time end and the time was adjusted:  As
  observerd, the last 4 jobs that had been successfully completed
  from the Job that finished at 3:31 P.M. the prior day reran from
  that specific job from the ClearCase scheduler.  On checking the
  scheduled jobs, the jobs indicate that they have completed
  running:  However, the process list shows that the jobs were
  running.
  
  
  Workaround:  None.
