Columns have types

I recently needed to import some CSV data into a Mongo DB database and while mongoimport makes it easy to import data from a variety of data sources, importing time stamps proved to be more complicated than I anticipated.

Initially, importing time stamps seemed like a trivial task, given that there is a way to describe a CSV field as a time stamp via the --columnsHaveTypes switch. The example in the docs seemed strange, though, because it didn't look like any date/time format one would expect and is shown as 15:04:05).
