Text file formatting

Hello

I have the attached text file that I would like to reformat.
I am only interested to work with the time, the data after the time can be dumped.
The script must calculate the time between each entry.
The file must look like this after processing :

00:10:32 ( 00:04:13 )
00:14:45 ( 00:00:45 )
00:15:30 ( next time.... )

As you can see, I have added the time between the entries.
e.g : 00:04:13 represents the time that passed between 00:10:32 and 00:14:45

Thank you in advance !

00:10:32 - 342333
00:14:23 - 2343242394809848754533
00:15:34 - 908942859445345435345345345

Look at this page for text manipulation

To calculate the difference, you'll need to extract the time in hour, minutes and seconds.  Convert to all seconds, do your math, then convert back to time format

I found an example here.  http://forums.techguy.org/software-development/757804-calculating-time-differences-batch-script.html

Can the times ever wrap around midnight?

Does this have to be a BAT solution, or would VB script be okay (a little easier to do the calculations there)?

Yes sir,. vb script would be perfect!

Also C# .NET is ok, I can work with that too

The time will never be 00:00:00 , if this is your concern
Bill PrewIT / Software Engineering ConsultantCommented:
Just a thought, would it be acceptable to do the following, rather than what you proposed?  I'm basically suggesting that you write on line n the difference in time from line n-1 to line n.  This would be a little cleaner to implement, since you could read line n and write it's value without having to read line n+1 first as you proposed.  So the result would be:

00:10:32 ( 00:00:00 )
00:14:45 ( 00:04:13 )
00:15:30 ( 00:00:45 )

Of course, this would be great !

Okay, give this BAT solution a try, adjust the file paths at the top for input and output files.

@echo off
setlocal EnableDelayedExpansion

REM Define input and outfile locations, initialize prior time value
set InputFile=x:\ee\EE26936537\EE26936537.in
set OutputFile=x:\ee\EE26936537\EE26936537.out
set LastTime=

REM Read input records, calculate elapsed time from prior record and write out
(
  for /F "usebackq tokens=1" %%A in ("%InputFile%") do (
    REM First record has slightly different logic
    if defined LastTime (
      call :TimeDiff !LastTime! %%A 
      echo %%A ^( !TimeDiff! ^)
    ) else (
      echo %%A
    )
    set LastTime=%%A
  )
) > "%OutputFile%"
exit /b

:TimeDiff [start-time] [end-time]
  REM Convert each time from hh:mm:ss format to a number of seconds
  for /F "tokens=1-3 delims=:." %%A in ("%~1") do set /A "t1=(1%%C-100)+((1%%B-100)*60)+((1%%A-100)*3600)"
  for /F "tokens=1-3 delims=:." %%A in ("%~2") do set /A "t2=(1%%C-100)+((1%%B-100)*60)+((1%%A-100)*3600)"
  REM Adjust if end time crossed over midnight
  if %t1% GTR %t2% set /A "t2=t2+86400"
  REM Compute difference in seconds between times
  set /A "d=t2-t1"
  REM Compute hours, minuts and seconds from total seconds
  set /A "hh=d/3600" & set /A "mm=(d%%3600)/60" & set /A "ss=d%%60"
  REM Left pad with zero if needed for formatting
  if %hh% LSS 10 set "hh=0%hh%" & if %mm% LSS 10 set "mm=0%mm%" & if %ss% LSS 10 set "ss=0%ss%"
  REM Build returned result in hh:mm:ss format
  set "TimeDiff=%hh%:%mm%:%ss%"
  exit /b
