My time comes in like this:

10:39:41:91
10:39:54.01

hours:minutes:seconds.milliseconds.

Is there a way to add and subtract times in this format ?

Thank you in advance.

Adding and Subtracting Times in Excel

1. Convert the time format to a recognizable Excel time format:

1. Select the cells containing the time values.
2. Go to the "Number" tab in the ribbon.
3. Select "Custom".
4. Enter the format "hh:mm:ss.00" (without quotes) in the Type field.

2. To add two time values, use the "+" operator between them:

1. Enter the formula "=A1+B1" (assuming A1 and B1 are the cells containing the time values) in a new cell.
2. The result will be in the same time format.

3. To subtract two time values, use the "-" operator between them:

1. Enter the formula "=A1-B1" in a new cell.
2. The result will be in the same time format.

4. For more complex time calculations, use built-in Excel functions such as "DATEDIF" or "TIME":

1. These functions allow you to perform various time calculations based on your specific needs.

Note: If there are any Excel formula examples in the original text, wrap them in the tag. If there is any macro or Visual Basic code, wrap it in the tags.

Hmmm... you give two different formats.

If they come in as milliseconds:

10:39:41.001

(.01 would be centiseconds, and :01 is something else entirely), then

A1: 10:39:41.91 (or 10:39:41.910)
A2: 10:39:54.01 (or 10:39:54.010)

use

A3: = A2 - A1

and format A3 with Format/Cells/Number/Custom hh:mm:ss.00 (hh:mm:ss.000)

They look to me like centiseconds rather than milliseconds.

If you correct the first one where you've mistyped a colon instead of the
decimal point, then you can add as normal.
=A1+A2 will give you the answer.
If the answer may go beyond 24 hours, custom format something like
[h]:mm:ss.00

That would be text for Excel, the custom format that would include
milliseconds in Excel is

hh:mm:ss.000

it's a period not a colon so you would need to convert them

=--SUBSTITUTE(A1,":",".0",3)


formatted as above would work for you examples but if you would have

10:39:55:211

then this might work

=IF(LEN(MID(A1,FIND(".",SUBSTITUTE(A1,":",".",3))+ 1,255))=3,--SUBSTITUTE(A1,":",".",3),--SUBSTITUTE(A1,":",".0",3))


remember to format as

hh:mm:ss.000

Doh! Forget it, I thought you had 3 colons there

Hmmm, if you wish to be able to add this in a way that you use mixed
separation symbols (as in your example for the "milliseconds" - i'd call it
rather hundreth of seconds) and still have a result displaying hours minutes
seconds and hundreths of seconds, you could use of course (for an addition
for example) a formula such as:

=TEXT(VALUE(LEFT(A1,2))+VALUE(LEFT(A2,2))+((VALUE( MID(A1,4,2))+VALUE(MID(A2,4,2))+((VALUE(MID(A1,7,2 ))+VALUE(MID(A2,7,2))+((VALUE(RIGHT(A1,2))+VALUE(R IGHT(A2,2)))99)59)59),"#0")&":"&TEXT(MOD(VALUE( MID(A1,4,2))+VALUE(MID(A2,4,2))+((VALUE(MID(A1,7,2 ))+VALUE(MID(A2,7,2))+((VALUE(RIGHT(A1,2))+VALUE(R IGHT(A2,2)))99)59),60),"00")&":"&TEXT(MOD(VALUE( MID(A1,7,2))+VALUE(MID(A2,7,2))+((VALUE(RIGHT(A1,2 ))+VALUE(RIGHT(A2,2)))99),60),"00")&":"&TEXT(MOD( VALUE(RIGHT(A1,2))+VALUE(RIGHT(A2,2)),100),"00")

This should work, but I'm sure there's other ways...:-) I'm just too lazy to
think today, and of course you would find a similar approach for
subtraction...
(hope I haven't missed a parenthesis somewhere - no means to test today)

Have fun,
Erny

You can leave out all the VALUE functions if you do calculations with them

=VALUE(LEFT(A1,2))+VALUE(RIGHT(A1,2))

is no different than

=LEFT(A1,2)+RIGHT(A1,2)

when it comes to the result, the calculation will force the text to number


also the value function is really totally obsolete except for pedagogical
reasons
same goes for datevalue and timevalue
