See below image attached .

I try to append multiple non-equidistant DFS0 :
from mikeio import generic
mikeio.generic.concat([File_name_2015, File_name_2016,File_name_2017,File_name_2018,File_name_2019,File_name_2020,File_name_2021], "Stream_flow.dfs0")

also when I try to append two non equidistant DFS0 files that have a time gap in between them the following error message.
'Gap in time axis detected - not supported'
See attached image.

Hi @elche6 , could you help me verify that the changes work as expected?

If you install the dev version from the main branch, it should work now.

pip install https://github.com/DHI/mikeio/archive/main.zip
