I have to find difference between two times that are in HHMMSS

TIMEA-TIMEB

TIMEA WE WILL GET FROM FILE1 WHICH IS SAME ALL THE TIME SAY 11:36:24


TIMEB WE WILL GET FROM THE OTHER FILE IN WHICH ALL THE TIMES ARE DIFFERENT SAY
09:00:00
09:10:00
10:00:00
10:12:34


SO WE REQUIRE TO SUBTRACT TIMEB FROM TIMEA
AS LIKE THIS
Code:
TIMEA     - TIMEB        = TIMEC
11:36:24  - 09:00:00     = 02:36:24
          - 09:10:00     = 02:26:24
          - 10:00:10     = 01:36:14
          - 10:12:34     = 01:23:50


WE HAVE TO MOVE TIMEC TO ARRAY SO THAT IT CAN BE MOVED TO TABLE

Hello,

Convert the time hh.mm.ss to seconds only. Perform the calculation and convert back to hh.mm.ss.
