I've tried everything, stumbled upon your post. Tried it. Still nothing. I've even gone as far as un- and re-installing.

Do not set future time, any server educated dude can tell you that, all your logs in the OS is screwup by it. same as past time, how will you catch a bug with wrong time stamp in a filter then it never get there, you might think its funny untill ( lets say a company you paid for get a hevay bill for waste of time and cant find a bug until they notice the time issue , you will still get bill for that and technician and company bill charge way more then standard per hour, unless you have 24/7 SLA, even the cheapest IT company is not that cheap as you think then its a company bill.

Even a private IT dude per hour + transport cost alot. ( why do you think OS have a sync with a time server regulary. ( and how will you fix things remote access with date and time wrong, you need to know all the fall grps in this. ) so many unspoken things IT know can rarely happend today much more frequent in the past crappy PC with battry and bios issue, dont expect a IT dude from today will catch such old outdated ways asap, will not be the first thing he will think on you did. ( and the taximeter is running )

This is not a joke.

ps.
So country date/time matter in the global communication with time zones, a well know issue among companys that use such.

Ohh why we are at it, i think we as steam user here actual solve some No connection in the past with this.

As i remember he admit he has time cheat in a game, atleast that better then nothing to know why it happend, but somehow effect system with it. ( so your search on topic is bad, but hey who cares today your own problem then you do such, right.

As i said there is no IT dude that will think ppl do this, OS has build in time syn-c check.
