I using ICETOOL for an SMF report but am having difficulty getting the
CPU TIME fields to display. The DATE and TIME fields print fine with
the DT1 and TM1 mask respectively but I cannot get the remaining
fields to print. I thought TC1 would be the right mask but I get
00:00:00.

Can someone help me please?

HEADER('DATE') ON(1,4,DT1,E'9999-99-99') -

Here are the field definitions:

1 SMFHDATE PL4 DATE RECORD WAS WRITTEN (0CYYDDDF)
5 SMFHTIME BL4 TIME RECORD WAS WRITTEN (TIME BIN)
9 SMO2CLCP CL8 CLIENT TASK CPU TIME (TOD FORMAT)
17 SMO2DBCP CL8 DATABASE CPU TIME USED OUT OF TOTAL CPU TIME
(SMO2CLCP)
25 SMO2NTCP CL8 NETWORK CPU TIME USED OUT OF TOTAL CPU TIME (SMO2CLCP)
33 SMO2OHCP CL8 OTHER CPU TIME USED OUT OF TOTAL CPU TIME (SMO2CLCP).
THIS IS CPUTIME NOT ASSOCIATED WITH ANY OTHER OPERATION.

Vendor manual explanation of its UNITS OF TIME format:

SMF data is expressed in time-of-day (TOD) format, which is an
unsigned 64-bit fixed
point number where bit 51 is the equivalent to 1 microsecond. The TOD
clock is a binary
counter where the bit positions of the clock are numbered 0 to 63.
This corresponds to the
bit positions of a 64-bit unsigned binary integer.

In the basic form, the TOD clock is incremented by adding a 1 in bit
position 51 every
microsecond. In models with a higher or lower resolution, a different
bit position is
incremented at a frequency where the rate of advancing the clock is
the same as if a one
were added in bit position 51 every microsecond. The resolution of the
TOD clock is such
that the incrementing rate is comparable to the instruction-execution
rate of the model.

Despite the vendor documentation above, they state that these
particular time fields are in MSEC8 format.

MSEC8 FORMAT
00000000 2647041A = 0.156784 sec
METHOD 1
1) TREAT THIS AS BINARY INT CONVERT TO DECIMAL
2) / 4096 = NUMBER OF MICROSECONDS (6 DIGITS OVER TO GET SECONDS)
METHOD 2
1) SHIFT RIGHT 12 BITS or 3 hex digits (THIS IS DIVIDING BY 4096)
2) CONVERT AS BINARY INT TO DECIMAL (6 DIGITS OVER TO GET SECONDS)

Is there a way to do this conversion with ICETOOL/DFSort?
