Python/Pandas Change time stamp to include milliseconds - python-3.x

I have a csv file that shows the time stamp like this:
I need to manipulate this csv in python so I'll end up with a 'Time Elapsed' column with millisecond resolution.
Keep in mind this time stamp goes longer than an hour so in Excel the time elapsed column just goes back to zero. I don't want that to happen.
I'm sure I'm not the first person with this issue but before you start flaming me, I have been looking for a few days and I can't find a solution.
That tells me I must be asking the wrong questions. I am new to Pandas/Python and I'm still not familiar with the lingo.
Here is the csv file I am using.

Thanks in advance.

How to get the time intervals and total time from a machine recorded minute to minute timestamps data sheet

This is Nikhil.
Here is where I got struck for days, Please help anyone.
I'm having a data of time stamps for every minute in the month.
And there is a corresponding data as well.
Based on the data, i need the time intervals and total operational time and total non operational time in excel.
in this excel file, input table is what im having and output data table is what im desired for....
Thanks you
Nikhil
Edit:
Thank you so much for the first answer,,,
But actually i asked half of the question only to made it understandable.
Now the real problem is - I want the time intervals which are in between the actual shift timings (That are 7:00, 15:00, 23:00).
So that I can calculate the individual shift working and non working hrs.
Please go though the second image's output format.

Thanks for your valuable time.
Done with formulas:
Identifies locations where "Operational/Non Operational" sections begin, then sorts them into final report with array formulas.
See link: (to note, array formulas do not work correctly in Google Sheets, must be viewed in excel. )

Excel time difference between dates jumping with day change

I am trying to calculate the time elapsed in a list of dates spanning 3 days.
When the date changes from 10/1/2021 to 10/2/2021 my time difference jumps up +30 days!!!
Here is the screenshot:
Does anyone know how to solve this?
I would like for line 454 to read 0:7:22:02.841.
Ultimately what I am trying to do is to use the the elapsed time as my X axis.
Here is the link for the sample files:

Thank you very much.

[EDIT2]: Had to move on to something else and never did find a solution for this. Thank you all for the comments.

Excel Time addition

First time poster and new joiner.
So I’m having a little difficulty is attempting to take a “lapsed time” with a format of 0:00:00 from a stated time (in this case I’m using a time stamp)
What I would like to achieve is the following.
Let’s say I attain some data from an external source that shows me the lapsed time someone hasn’t been logged In from their expected time. Now unfortunately the time due isn’t readily available so I want to put in A1 (CTRL + shift and ; for my time stamp) and then in B1 I want to minus the lapsed time. And in C1 a subtraction formula that will give me (there or about a the time that should be due to log in)
The issue I’m facing is this, I’ve tried a simple minus, a TIME function and both give a value error
I’m unsure whether firstly the fact that my time stamp being only hours and minutes is an issue but also when I attempt to remove the seconds from the lapsed time it won’t easily format out without manual input from me.
I feel like I’m being stupid here but cannot seem to get say;
14:55 to minus 0:25:00 to give me 14:00 !!
For clarity I have tried to format the time to include seconds but still not use...
Is there an easy way to conver the lapsed time to minutes for easier use of TIME ?
14:55 to minus 0:25:00 to give me 14:00
I think you wanted to say "... to give me 14:30".
Well, you can do subtraction of time values:

generating random time entries before and after midnight Excel

I am trying to generate random time entries between two time limits in Excel. the problem i am facing is the generation works fine with the same day time calculation as soon as the time passes midnight, Excel gets confused and give me wrong values values. I need to generate random entries then match it to the closest value it has in the time series given in the sample workbook. Can anyone help me?
Workbook
Try this :
=IF(ROWS($D$10:$D10)>$F$4,"",IF(HOUR($C$4)<HOUR($C$5),TIME(RANDBETWEEN(HOUR($C$4),HOUR($C$5)-1),INDEX({0,15,30,45},RANDBETWEEN(1,4)),0),IF(HOUR($C$4)=HOUR($C$5),TIME(HOUR($C$4),INDEX({0,15,30,45},RANDBETWEEN(1,4)),0),IF(HOUR($C$4)>HOUR($C$5),TIME(IF(RANDBETWEEN(0,1)=1,RANDBETWEEN(HOUR($C$4),23),RANDBETWEEN(0,HOUR($C$5)-1)),INDEX({0,15,30,45},RANDBETWEEN(1,4)),0),1))))
Hope you can share the results.. (It'll benefit others too) (:

Repair incorrectly formatted time 'hh:nn:ss' when h=0

I'm doing a report which calculates people's time to determine their pay. We pull reports from our servers and paste them into Excel to do the calculations. I have run into an issue when pulling the data: if the time they logged in for was less than an hour our formula is not working:
=IF(E159="","",((HOUR(E159)+(MINUTE(E159)+(SECOND(E159)/60))/60)))
This gives an error (#value) if the time is :34:15, but if it's 00:34:15 then it's fine.
Formatting the cell does not appear to work.
I'd like to go through this column and add the 00 to all values missing it, and I need some help or guidance from there.
Another question on SO looks like it may help, but I'm unsure on how to use it.
Assuming that The tiem is in cell E159 from your above formula, you can append a 0 to the start of the time. This will fix all the times that have the hour missing and won't affect the other lines.
="0"&E159
You can then replace all of the E159 references in your original formula with this edit so that it looks like this:
=IF(E159="","",((HOUR("0"&E159)+(MINUTE("0"&E159)+(SECOND("0"&E159)/60))/60)))
While it's hard to read, it does the trick.
While that answers you question.. I think that there is a better way to achieve this formula.
It looks like the end result you're looking for is the time converted to hours, with mulutes and seconds as a decimel to the next hour. You can achieve this by doing:
=E159*24
Which will give you the same result as your original formula.
And then to combine that with my first answer to get a formula that looks like:
=("0" & E159)*24
This approach is much easier to read / edit and provides the same output.
Why This Works
Excel stores all dates as whole numbers, and all times as a decimel % to a day.
So when Excel is stores 12 hours it saves it as .5 because it is half of a day.
By dividing the time output by 24 we are converting the entire time value down from a % of day to a % of hours.
