Sort dates and hours chronological

Hello guys,

Please help me to order chronological the dates from the document attached.
I tryied Format Cells -> Number -> Custom -> and enterd more options like dd/mm/yyyy hh:mm ; mm/dd/yyyy hh:mm etc with no result
The purpose is to display after 1/10/2018 23:56 ( line 359) -> 2/10/2018 00:00(2 october 2018), not 1/11/2018 00:00 ( 1 november 2018) like in the doc.
I need to do this for all 6 months from the document.

Thank you and have a good day!

Here is the attach, sorry for spam

And what date is 14/03/2019? I don t have problems with windows time.

How do you explain the following lines?

Line 28861 14/03/2019 23:56

Line 28862 14/10/2018 00:00

Unfortunately, no result.
In column A I have date and time, and in B,C,D,E other variables.
I tried in the document attached where only column A is populated, but it doesn`t work.

As 'KOKOSEK' as already pointed out it is most likely your regional settings causing your problem.
The Romanian 'short date separator' is a '.' (point) NOT '/' .
You need to convert or replace the date element.
Where was the original data sourced from ????

It worked!!

Thank you very much and wish you all the best!
