FluentCassandra selecting timestamp range with CQL
===

I have a method in my DAL that selects objects with CQL query. I'm trying to pass time interval as follows:

    //FilterStartTime, FilterEndTime are of type DateTime, stored in config
    // converting DateTime to unix timestamp
    var start = (FilterStartTime - new DateTime(1970, 1, 1).ToLocalTime()).TotalSeconds;
    var end = (FilterEndTime - new DateTime(1970, 1, 1).ToLocalTime()).TotalSeconds;
    // UploadedOn is of type timestamp
    var selectQuery2 = "SELECT * FROM MyColumnFamily WHERE DocumentKey=" + key
                                + " AND UploadedOn>=" + start
                                + " AND UploadedOn<=" + end;
    //"SELECT * FROM MyColumnFamily WHERE DocumentKey=000001 AND UploadedOn>=1341093600 AND UploadedOn<=1343599200"
Database contains record that is in specified range. Above query returns 0 elements though. CQL usage is not a requirement, so i might have been used API, but there is no Fetch method anymore (http://stackoverflow.com/questions/5325035/fluentcassandra-range-selection-problem), and i still want to know what's wrong with my sql query.
