Control STRING to DATE/TIME Conversion?

Hello, 

When changing a STRING type column to a DATE/TIME type colum using:

#"Changed Type" = Table.TransformColumnTypes(
    #"Reordered Columns1",
        {
            {"weatherTime", type datetime}
        }
),

... some kind of "auto-magic" is applied to the time that I DO NOT WANT. In this case, the auto-magic is changing the string from

to 

which is a -7hr translation for some reason.

How do I control this conversion?

Thank you
