Readtable() turns time stamp into decimal

I have a table with 40 columns. When I use readtable() it turns the time stamps into decimals and I don't know what the decimals mean. I need to extract the time stamps. And also I don't want the headers, but it reads them anyways.

data = readtable(filename, 'ReadVariableNames', false); %read in data file

Original excel file:

How the data looks in matlab:

add 'headerlines', 1 to readtable

Thanks @Walter Roberson! Now any idea about the time stamps? I can work with the decimals too, if I just understood what they meant.

This appears to be a problem with Excel files that use the ‘AM/PM’ time desiignations, and still exists in R2020a. The best way to deal with it (in my experience) is to force Excel to write it as a text file to a different file name. Then, use readtable with the text file with detectImportOptions since it allows formatting options for the time columns in text files that do not exist with spreadsheet files.

The numbers are fractions of a day, so you can

Time = days(FractionsOfADay);
Time.Format = 'hh:mm:ss';

Thank you both for helping me out!

Walter, that was exactly what I was trying to do. Thanks so much!
