offset local time

An offset is simply the difference between UTC and local time, whereas the time zone is a named set of rules describing how the offset changes over time.

偏移量仅仅是UTC和本地时间之间的差值，而时区则是一个具名的规则集合，描述了偏移量该如何随着时间的变化而变化。

Therefore a time in time zone 0 (GMT at the time, as there was no UTC yet) would have an odd time offset when represented as local time for Yekaterinburg (Russia).

因此时间时区0(格林尼治时间，因为没有UTC)将有一个奇怪的时间抵消叶卡捷琳堡时表示为本地时间(俄罗斯)。

Links nodes not be necessary to send messages to the each other, known of the two nodes 'time can determine the scope of the third node's offset and drift, then determine its local time.

链路中节点同步时并不是必须通过接收发送消息的方式，由已知的两节点的频偏和相偏范围就可以确定第三个节点频偏和相偏范围，从而确定其时间范围。
