Ah. The facts that the formula returned "FALSE" and the display not changing when you go to Format>Cells both (independently) tell us that your data is not stored as times, but as strings.
We can convert your data to actual times by using the ol' 'Times One Fix' (I'll explain later) but the problem is that Excel will assume that 27:40 is Hours and Minutes, not Minutes and Seconds.
There are tons of ways around this. But the one that strikes my fancy at the moment is to use a formula in a 'helper column'. In an empty column to the right of all imported data, use this formula:
[COLOR=blue white]=if(len(A2)=5,("00:"&A2)*1,if(len(A2)=2,("00:00:"&A2)*1,A2*1))
[/color]
[tab](replace A2 with the appropriate cell reference)
The result won't look like times at all - that's ok (See Skip's FAQ). Format the cell as Custom, [h]:mm:ss. The brackets around the hours will force Excel to display the total number of hours even if the time exceeds 24 hrs. Now drag the formula down as far as necessary.
If you like, you can select the entire column then Copy, Paste Special > Values to replace the formulae with actual time info.
Give us a shout if you run into any trouble.
PS – Oh yeah, about that ‘times one fix’: You can type a 1 into any empty cell to the right of the imported data. Then copy that cell. Now select the cells that are giving you trouble (supposed to be times but aren’t) and Edit > Paste Special > Multiply & Values. That will force the little buggers into actually behaving as numbers. But, as I said earlier, that won’t work straight out in your case because Excel will just assume that 27:40 is hours & minutes. Even worse, if you ever have data that is just seconds, Excel will assume that 27 is days instead of seconds. That’ll throw off your data!
If your head is spinning right now, do yourself a favor and read FAQ68-5827 to learn about how Excel deals with Dates and Times.
