[QE-users] weird CPU and WALL time report

[IORI, Federico]

 Hi all.
Sorry to bother by such a question but I found several times  with version
6.3   a weird correspondence between CPU time and WALL time. (see attach
file reports)

For example in several runs I got at the end of my pw.out file

*PWSCF        :     1h12m CPU       12h 1m WALL*

*      16h*

while the REAL wall time obtained as the difference between the starting
time on the header and the ending time at the bottom of the output file is
really 1h 12m in this case

It seems to me the numbers of the  wall time are reversed wrt the CPU time
in the writing procedure.
I tried to find the routine printing this last PWSCF line but I cannot find
it.

My questions:
1) is normal this behaviour?
2) does someone already noted it  ?
3) should I start to worry about  my compilation ?
4) can you tell me how is called such routine printing the PWSCF execution
time?

Thanks for now!
With the best
