Smaller ETT datasets

[hansk0812]

The ETT{h1,h2,m1,m2} datasets are shorter than the official ETT-small dataset which spans for 2 years. The official dataset from other sources seem to go from 2016-07-01 to 2018-07-01 excluding the last few dates but the datasets from this repo only go up to 2018-02-20. Am I missing something?
