Finding Random Time between given range using Randbetween function in Excel - excel

I wish to find a Random Time between a given Time range containing Time format HH MM SS using a Randbetween function from excel. I just google around and came to know below function helps to get the result i need. but i need an explanation as i dint understand how this formula works. eg i dont know why it use 0 here and multiply and divide by 1000
=(RANDBETWEEN(0,($B$14-$A$14)*10000)/10000)+$A$14
B14 is ending time eg: 8:30
A14 is starting time eg: 7:30

Say we have two genuine times like:
9:15:23 AMand2:34:21 PM
If we first convert both times into integer seconds, we can use RANDBETWEEN(). Place the values in A1 and A2
then in B1 enter:
=A1*24*60*60
and copy downward.
In C1 enter:
=randbetween(b1,b2)/86400
and format as time:

Time comparison in Excel

This should be straight-forward, I'm trying to compare if a value of time is less (or more) than another.
=IF(A1 > B1,True,False)
Where A1 and B1 are a number of hours and minutes in [h]:mm format.
A1 is 48:45 in [h]:mm format
B1 is 50:00 in [h]:mm format
If I wanted to replace B1, in the formula, with an absolute time (say of fifty hours) than I thought the answer might be either:
=IF(A1 > TEXT("50:00", "[h]:mm"),True,False)
=IF(A1 > TIME(50,00,0),True,False)
But it's not. Any ideas?
TEXT returns Text and not a number and as such it would always be greater than the time.
But we can turn it into a number by simple multiplying it by -1*-1
=A1>--TEXT("50:00", "[h]:mm")
But then the simple would also work:
=A1>--"50:00"
TIME returns the time portion and as such:
TIME(50,00,0)
resolves to 2:00 or 0.0833333 as it is the time part of the number without the integer.
So we can just do some simple math:
=A1 > 50/24
now the 50/24 will resolve properly to 2.083333
The VALUE function can come in handy for you. It's the build-in function to turn text-strings that represent a numeric value into an actual numeric value, so:
=A1>VALUE("50:00")

Calculation of a time interval a time list until the next time mark is more than x minutes away

This is the data sample we have where A is a timestamp, B is the starting time, C is the ending time.
~~~A~~~~~~~~~~B~~~~~~~~~~C~~~~~~~~~
14:44:09 14:44:09
14:45:03
14:45:43
14:46:32
14:47:41
14:48:22
20:03:35 20:03:35
20:07:03
20:13:41
20:14:12
20:15:06
20:16:12
21:13:41 21:13:41
21:14:52
21:35:18
At C1, I want to have the timestamp 14:48:22. That time is specifically chosen by a rule that states "if the time difference between two timestamps is greater than 10 minutes, the smaller timestamp gets written at the beginning of that series" which would be C2 in this case. To illustrate my point, see below.
~~~A~~~~~~~~~~B~~~~~~~~~~C~~~~~~~~~
14:44:09 14:44:09 14:48:22
14:45:03
14:45:43
14:46:32
14:47:41
14:48:22
20:03:35 20:03:35 20:16:12
20:07:03
20:13:41
20:14:12
20:15:06
20:16:12
21:13:41 21:13:41 21:35:18
21:14:52
21:35:18
Thank you in advance.
Column B is relatively easy:
B1 is simply =A1
B2 is =IF(A2>A1+TIME(,10,),A2,"") which checks the time next to it against the time previously, and if it's over 10 minutes, put the time in the cell, else put an empty string
The C column is a little more interesting
First, we need to find the next time shown in the B column, which, using the answer from here, gives us:
INDEX(B2:B15,MATCH(TRUE,INDEX((B2:B15<>""),0),0))
now we have the value, we use MATCH to find it in column A, subtract 1 from the location to get the previous time, and report that.
=INDEX(A2:A15,MATCH(INDEX(B2:B15,MATCH(TRUE,INDEX((B2:B15<>""),0),0)),A2:A15,0)-1,0)
We wrap it in an IF statement to make sure it's blank when the corresponding cell in B is blank, and we end up with a very horrible looking formula like this in C1:
=IF(B1="","",INDEX(A2:A15,MATCH(INDEX(B2:B15,MATCH(TRUE,INDEX((B2:B15<>""),0),0)),A2:A15,0)-1,0))
The only drawback to this equation is that the last result gives an #N/A, but you can either just fix that manually, or wrap the formula with an IFERROR statement, giving the behemoth equation of:
=IFERROR(IF(B1="","",INDEX(A2:A15,MATCH(INDEX(B2:B15,MATCH(TRUE,INDEX((B2:B15<>""),0),0)),A2:A15,0)-1,0)),MAX(A:A))
Copy B2 down, and C1 down to get the result you requested. adjust the B15 and A15 in the formula to match your full data set.

How to change a timespan into decimal format in excel?

I have the following problem. In my excel sheet, I subtracted two time values to get its timespan.
Here is an example:
16:30-8:00=8:30
the cell format is a time so its all fine. Now the problem:
I need to show the timespan also as a decimal. So the 8:30 should be a 8,50
Anybody know how to do this?
Use =24*(B2-C2), where the cell where calculation happens should be formatted in 2 decimal number format .
B2= start time.
C2= End time.
Try this
Say A3 is 08:30, you can put this in A4
=HOUR(A3) & TEXT(MINUTE(A3)/60, ".00")

Converting MM:SS.ms to seconds using MS excel

I am looking for a neat way of converting a cell from
Minutes:Seconds.Milliseconds to
Seconds.Milliseconds
i.e.
11.111 = 11.111
1:11.111 = 71.111
I have something in place at the moment but its a bit hacky and I am sure there must be some nice excel feature to do this for me :P
Thanks!
Do this:
Place values 0:0:11.111 and 0:1:11.111 in cells B3 and B4 respectively.
Now format it to account for the milliseconds... Select cells B3 and B4, right click and choose Format Cells. In Custom, put the following in the text box labeled Type:
[h]:mm:ss.000
Now on cell C3 put the following formula:
=B3*86400
Fill C4 with the same formula...
Format column C as Number with 3 decimal places.
You're done! :)
Here's a screenshot of the attempt I made and that worked:
Edit:
As you wanna enter only MM:SS.ms you can format the entire B column with a custom format like: mm:ss.000. Now you can enter values as 02:11.111 and it'll convert it accordingly giving you 131.110. Hope it helps.
say your time is in cell A1, place this formula in B1
=IF(LEN(A1)>5,VALUE(TEXT(A1,"[ss].00")),A1)
If the time is less than a minute it outputs the time unaltered, greater than 1 minute it converts it to seconds & milliseconds (2 decimal places).
This will only work if your time in A1 is 10 seconds or greater.

formula to minutes and seconds down into total amount in seconds

I am looking a formula for excel that minus a feild called end time by field start time and answer will show as the total amount of seconds the calls lasted.
For example i have call that ended 04:04:35 and started at 03:51:51 and i need to how many seconds that would be in total and instead of working by calucator would like to know if there fourmula to do it
thanks
simon
The easiest is to set the two cells as time (hh:mm:ss) then subtract them.
Put the result on a new cell, formatted as a number and multiply the result by 86400.
See this post for the explanation
EDIT: the final cell has to be in number format, something like this:
A B C
Cells 1 03:51:51 04:04:35 =(B1-A1)*86400
Cell format: hh:mm:ss hh:mm:ss number
