I have a log file which contains time stamps and logs.
For example
01:03:45 abc
01:03:47 bcd
I want to change time stamp by some time (for example 1 hour, 2
minutes and 3 seconds), so I want to increment each time stamp by
01:02:03.

function! IncTime(t, increment)
let l:i_h = matchstr(a:increment, '^\d\d')
let l:i_m = matchstr(a:increment, ':\zs\d\d\ze:')
let l:i_s = matchstr(a:increment, ':\zs\d\d$')
let l:h = matchstr(a:t, '^\d\d') + l:i_h
let l:m = matchstr(a:t, ':\zs\d\d\ze:') + l:i_m
let l:s = matchstr(a:t, ':\zs\d\d$') + l:i_s
if l:s > 60
let l:m += (l:s/60)
let l:s = l:s % 60
endif
if l:m > 60
let l:h += (l:m/60)
let l:m = l:m % 60
endif
return matchstr('0'.l:h, '..$').':'.matchstr('0'.l:m,
'..$').':'.matchstr('0'.l:s, '..$')
echo l:h . '/'.l:m.'/'.l:s
endfunc
" a test harness
$?^data:$?,$s/^\d\d:\d\d:\d\d/\=IncTime(submatch(0), '01:02:03')
finish
data:
01:03:45 abc
01:03:47 bcd
01:03:59 bcd
01:59:59 bcd

The above function takes a time as a string, and an increment as
a string, and then returns the resulting time. The line under "a
test harness" performs a demo, converting the lines at the bottom
(from "data:" to the end), incrementing them by your mentioned
"01:02:03".
Enjoy...
