Subj:   Re: Decimal or time in PI
 
From:   Geoffrey Rommel

  Also, there was a discussion on 'time is bad for PI'? True? What was the reason?  


@
  Because you need the exact value to be able to use the PI and you probably don't know the exact time up to the second/millisecond.  



And also because in some installations TIME fields were not being hashed properly: all values hashed to the same AMP. This has been corrected in more recent releases. We do have a few tables that are hashed by timestamp(0), but they are used mostly for logging and reporting, not for searches by PI.
