我也有这个疑问，请问您是怎么解决的呢

It's the timestamp information.

Also, it seems that a lot of people confuse "mark" with "mask". (https://github.com/zhouhaoyi/Informer2020/issues/158#issuecomment-848691957)

Many thanks for your answer, so does that mean batch_x is the original sequence info, and batch_x_mark is the timestamp information which is extracted from the original sequence?

Yes, it used the time_features to create the timestamp infos.
