[QUESTION] Identify TIME Column Type?

Thank you very much for writing (and open sourcing) this really great library! I am working on incorporating this into Apache Drill which will enable users to use Drill to query SAS files with SQL. I ran into a small issue which I can't seem to figure out. I need to get the schema of the data. Right now, I have a `for` loop that iterates over the columns and maps them to the correct type of Drill vector.

```java
List columns = sasFileReader.getColumns();
```
The issue I'm running into is with `TIME` formats. With the code above, parso only seems to return times as `longs`. Is there any way to programmatically identify whether a column is a time and not a `long`?

Here's a link to my code: https://github.com/cgivre/drill/tree/format-sas
The relevant code can be found in the `contrib/format-sas` folder.

Thanks!
