chronologically

Arranged chronologically, it begins with the novel’s primordial period — everything up to 1800 — and then marches century by century into the present..按年代排列，它开始于小说的产生时期--一切回溯到1800年--然后一个世纪一个世界的进行到现在。

This means that data may appear two or more times in the log, but as the log is chronologically advancing, the most recent data is viewed as the active data..这意味着数据可能在日志中出现两次或更多次，但是由于日志是按时间先后顺序发展的，最近的数据被视作活动数据。
