And if you use GMT, as I mentioned earlier, unless some cosmic event happens that disturbs the flow of time, there is no such thing as a GMT time that does not exist, since GMT ignores transforms like daylight savings.

Not really. We use GMT (Greenwich, the "G" in GMT, is in North London) here in the UK and we do have daylight savings. GMT without daylight savings or any other features are commonly referred to as UTC nowadays.
