How may I import an excel sheet without letting zoho automatically change the time format in a column??? we don´t use dates

I am importing an excel file from my computer to Zoho reports. Our column says start time and the other finish time. There the data is in the format of 24 hours in each column, indicating hh:mm:ss. Please advice of how to mantain the format and not changing into the month year time format (which by the way is different as the one that we import)...


Kind regards
