RE: How to tell when an OS was installed?

Here's what one of my superceded TLs looks like on our V5R1 box which was just 
upgraded from V4R5 on Aug. 28:

Product ID/PTF ID  . . . . . . . . . . :   5722999  TL01086  
Release  . . . . . . . . . . . . . . . :   V5R1M0            
                                                             
On order . . . . . . . . . . . . . . . :   No                
PTF save file  . . . . . . . . . . . . :   No                
PTF status . . . . . . . . . . . . . . :   Superseded        
Superseded by  . . . . . . . . . . . . :   TL04300           
Status date/time . . . . . . . . . . . :   08/28/05  19:02:40

However, on a V5R2 system that was recently restored from a SAVE 21 backup, 
those superceded TL PTFs have no dates, similar to yours:

Product ID/PTF ID  . . . . . . . . . . :   5722999  TL02155
Release  . . . . . . . . . . . . . . . :   V5R2M0          
                                                           
On order . . . . . . . . . . . . . . . :   No              
PTF save file  . . . . . . . . . . . . :   No              
PTF status . . . . . . . . . . . . . . :   Superseded      
Latest superseding PTF . . . . . . . . :   TL05123         
Superseded by  . . . . . . . . . . . . :   TL04244      

I suspect that doing the system restore wipes out those dates.

Oh well. Good luck with this one. Have you posed this question to IBM?
