Millisecs() resets to zero in think it's 30 years time. It's a similar problem to the Y2K bug of clocks, but moreso. The timer counts up to umpteen billion and then rolls-over, at which point timer based functions go pear-shaped and all hell breaks loose and just like the year 2000, all computers stop and the world is thrown into anarchy and a new Dark Age as we regress to animals without our computers working.
