Retrieving data between two timestamps

[Renato Marroquín Mogrovejo]

Hi all,

I am having some problems while retrieving some events from a column
family I have created.
My column family has been created as follows:

create column family click_event
  WITH comparator = UTF8Type and
  column_metadata = [ {column_name: event, validation_class: UTF8Type} ];

My table is populated as follows:

 list click_events;
-------------------
=> (column=start:2013-01-13 18:14:59.244, value=, timestamp=1358118943979000)
=> (column=stop:2013-01-13 18:15:56.793,
value=323031332d30312d31332031383a31353a35382e333437,
timestamp=1358118960946000)

I have two questions here:
1) What is the timestamp column used for?
2) How can I retrieve this timestamp column using Hector client?

Thanks in advance!
