其他参与者原话davidonpda原帖 ↗时间上允许多大的偏差才能正常工作？
How big of a margin on the time is allowed for things to work right.
容许偏差是 2 小时。
The margin is 2 hours.
这个问题会在 SVN rev 141 和下一个版本（0.3.11+）里解决。如果你的时钟偏差超过一小时，它会弹出消息框提醒你。
This should be solved in SVN rev 141 and the next release (0.3.11+). It'll pop up a message box alerting you if your clock is off by more than an hour.
