Ok, what on earth is actually the question?
I'm pretty sure you (NissanSkylineN1) are referring to the time on GTP being incorrect to your actual time? Seeing as this is in site feedback I assume that's the actual question but it's really unclear what is actually going on here.
Then Crow has told us about the worlds axis being on a tilt and not in anyway linked that to Daylight Saving Time (DST) which I'm sure Nissan is aware of anyway, surely anyone on GTP is old enough to know by now that the clocks change by an hour every 6 months or so? Either Crows post is way off the point or this was posted in the wrong place (doubtful) and Crows post is just a poor explanation of what's going on.
Anyway, this needs more clarification on what the actual problem is, but check your time settings Nissan by going into My GTPlanet and then Edit Options, make sure you're in the correct timezone and set DST correct option to automatic and you should be good to go.
