Adding a function module into a SQ01 Query

Question

Hi ABAP Gurus,
I was trying to extract few dates from TSEGE Table, by linking the VTTK - HANDLE. We are trying to look at maintaining dates of shipment that were not previously used in our company.
When I tried extracting the dates from TSEGE, they come as timestamped UTC. I was told to use the function module IB_CONVERT_FROM_TIMESTAMP with CET in a query by an external consultant we use for our services. I am familiar with creating simple queries in SQVI and convert them to SQ01, also I know to create queries in SQ01 itself. But do not know how to add a function module into an SQ01 Query.
After checking a few threads, I realise that I should be creating a field and entering the code of the function module.
Is there any way, anybody could instruct me in simple terms how do I go about adding a function module.
Your help will be greatly appreciated.
Thanks in advance!

Dear Jogeswara,
I have after reading a few threads, understood this small code and changed to my specification
To convert UTC Start time from TSEGE
CALL FUNCTION 'IB_CONVERT_FROM_TIMESTAMP'
  EXPORTING
    I_TIMESTAMP = TSEGE-EVEN_TSTFR
    I_TZONE = CET
  IMPORTING
    e_datlo = date
    e_timlo = time
To convert UTC Start End from TSEGE
CALL FUNCTION 'IB_CONVERT_FROM_TIMESTAMP'
  EXPORTING
    i_timestamp = TSEGE-EVEN_TSTTO
    i_tzone = CET
  IMPORTING
    e_datlo = date
    e_timlo = time
I hope the above codes are correct. If yes, I have a doubt: TSEGE-EVEN_TSTFR & TSEGE-EVEN_TSTTO have different time in the same field, "Actual" & "Forecast", which is determined by TSEGE-EVEN_VERTY wherein 1 is Actual and 0 is Forecast. Is this something I would have to put in the code, or something that would work in the query "Selection Fields"?
Thanks again!
