Grouping ot items incorrect in line report

-- HikaShop version -- : 4.3.0
-- Joomla version -- : 3.9.23
-- PHP version -- : 7.3.27

Hi,

This problem concerns the legacy dashboard.

First I published a table report of the sales in a month.
Period: this month
The sales figures are displayed correctly.

Then I published a line report of sales this year. The items are grouped per month.
Alas the resulting sales figures differ from the table report.

Looking into the cause of the difference I discovered that the exact start time and end time are incorrect when grouping per month in the line report.
The start date is not March 1 00:00 but Febr 28 22:00 and the end date is March 31 22:00
So the month is pushed back 2 hours!

I tested several months, the same thing happened every month.
And this problem also arises when grouping per week.

The selected date type in the line report: created

Please advise.

Udo
