How to read real time from SAS log file

[zqkal]

I have an automated process that runs proc means on 24 million observations and 10 class variables in SAS Grid environment. 

I looked at the real time on the log and couldn't understand what it say. 

real time           1:25:43:10.19 
cpu time            10:20:23

How would you read the real time: Is it [day],[hours], [min], [secound], [microsecound] ?

[Ksharp]

It is [hours], [min], [secound], [microsecound] . use informat STIMER. to input it .

And given that, it seems that you have bottleneck in your environment.
FULLSTIMER might give some more clues, but you probably need to use OS monitoring to get the full picture (basic OS measures are available in Environment Manager if you have that installed/configured).
