Adding date and time

I am trying to add a date and time field to this query, but am really having problems with it. Would appreciate any help I can get. I am new to SQL and don't quite understand everything yet.

use Brians

DROP VIEW FanSpeeds
GO
CREATE VIEW FanSpeeds AS
SELECT NodeTable.node_id, NodeTable.label, Histories.hist_id, Histories.var_name, Data.pt_data
FROM NodeTable
INNER JOIN Histories ON NodeTable.node_id = Histories.node_id
INNER JOIN Data ON Histories.hist_id = Data.hist_id
WHERE NodeTable.node_id = '103117-549' AND Histories.hist_id BETWEEN 60 and 64
GO
SELECT * FROM FanSpeeds order by hist_id
