#540 time remaining is improperly calculated

[Eric Peterson]

When hosting a game with a time limit on the metaserver, the time remaining in the game is improperly displayed to other users present. It jitters up and down and decreases much more slowly than the actual time remaining, as calculated by the in-game clock on the host. It's not clear to me whether this is an AlephOne bug or a Mariusnet bug, but it warrants investigation.

This hasn't been noticed before because people don't typically host 999 minute games of One Way 2. The time limit appears to have to be quite large to see an appreciable discrepancy. Still, a bug's a bug.
