Import CVS Time

I am having an issue importing from a CSV file regarding time fields. Everything else in my file imports just fine include the date fields. However, I need my items to have valid time fields along with the date and no matter what I do I get some type of format miss match error on the import options and those columns don’t import unless I create a text field. But again, I need these items to have valid time fields so I can view them on a Calendar with both the correct date, start, and end times of these items as they are events. Any thoughts on how to best format a CSV file for time imports?
