Please consider that the time ranges could be different for different day, for example:
tTime table:

StartTime            EndTime
2010-01-01 02:00     2010-01-01 06:00
2010-01-02 19:00     2010-01-02 24:00

    I’m not near my computer with MS SQL on it but this should do the trick:

    SELECT tData.*
FROM 
    tData
    LEFT JOIN tTime
        ON CONVERT(VARCHAR(10), tTime.StartTime, 101) = CONVERT(VARCHAR(10), tData.FooTime, 101)
WHERE
    tData.FooTime BETWEEN tTime.StartTime AND tTime.EndTime

    Essentially join the two tables based on the Date (without time) portion of the StartTime and FooDate, then just use a BETWEEN in the WHERE clause.

    As I said, I can’t test this on this laptop but I’d say it’d work.

    Edit: This assumes that there is only 1 day per row in the tTime table as per your example

    EDIT: Just remembered that you should be able to use BETWEEN in a JOIN criteria, so this should be better:

    SELECT tData.*
FROM 
    tData
    INNER JOIN tTime
        ON tData.FooTime BETWEEN tTime.StartTime AND tTime.EndTime
