Elapsed: 367.55 (mins)
DB Time: 4,879.90 (mins)
I am looking at the "DB Time" of 4879.90 minutes; and comparing the value with my elapsed time - not sure if its ok to see a higher DB time than elapsed time.

Elapsed time is the duration of your snapshot. DB time means CPU time consumed during that elapsed time. So you should have definitely more then 4879.90/367.55 >= 14 cpu. Now check your cpu utilization , let's say if it's 50%, that means you got 14*(100/50)=28 cpu.

I am not so sure that snapshot differentiate between different cpu's . I never have seen db time higher than elapsed time. Could it be a bug ?

No i do not think it's a bug, if you got a very busy system(cou intensive operations)with multpile cpus, you can see it.
