In an excel file, I have a column of time data as
12:00:00 AM
12:00:01 AM
12:00:02 AM
12:00:03 AM
12:00:04 AM
12:00:05 AM
when I import this column to Matlab, the data look like:
0
1.15740740740741e-05
2.31481481481481e-05
3.47222222222222e-05
4.62962962962963e-05
5.78703703703704e-05
and when i use the datastr to convert, the results look like this:
00:01:00
00:01:01
00:01:02
00:01:03
00:01:04
00:01:05
Where does the additional 1 minute come from?? I suspect it's about the accuracy of the numbers. Not sure though.
Please help. Thanks!

Excel stores date as serial date numbers, which are not identical to Matlab's serial date format. See http://www.mathworks.com/matlabcentral/answers/64198#answer_75809 for an answer.
