Need help importing CSV data.

Need help importing CSV data.

My company would like to use ZOHO Reports for reporting. We have daily files to import that can contain up to 7500 records. The daily file is a CSV file. We only need 12 of the 40+ fields for this file. I know how to select which fields I need. We have been using Excel but it is too cumbersome to do the reports needed on a weekly basis. Excel does convert the data very easily. I have 4 fields that are giving me a challenge... Date field... the CSV file only contains the month and day.
"MMM DD" format. When imported as a date field ZOHO some how all the dates are the same. ie DEC 30, DEC 31 and JAN 01 all import as 01/01/2014. Imported as a text field I get all the correct days; however now I do not have the year needed for reporting. Is it possible to import my data and force an additional field (not contained in the CSV file) to be the current date that the import is being performed. Say ImportDate? I also have 3 time fields that don't contain or need to have the date. 2 are specific times and 1 is a duration of time. All formatted as HH:MM:SS. I believe I have figured out how to deal with these fields but any additional help would be welcomed. Thanks!
