seems that you assume continuous recordings , forgetting about duty cycle
bub observed on dataset test_sample_DC , reshaping 30s file to 15s , there is a duty cycle : 30s recording every 5 mins
last timestamp of reshaping is then 2001-12-21T17-14-45_000.wav , while it should be the same as original ones: 20211201_201000.wav
