Since GetTickCount is modulo 48 days anyways (env.TickCount has half the
resolution since it is always positive), the thing should *NEVER* be
used for uptime calculation. The only correct use for tick count is to
calculate the change in time, for changes known to be relatively small.
This doesn't make the method much slower, so its not that bad. But it
sure is alot of complexity for something that should never be used.
