        <pre>Description:
I use a spreadsheet between windows and linux and it does some date
calculations.  I noticed that some entries on the Excel side had a value of
3/21/2019 and on the linux side had a value of 3/20/2019.  So when I checked
the two systems were converting a date using the function Date(Year(xxx),
Month(xxx), Day(21))
On excel the value was 03/21/2019  on Libreoffice in linux it was 03/20/2019. 
This caused some values to be incorrectly calculated.  Everything catches up by
the end of the month, but seemed wrong.

Steps to Reproduce:
1.Use the date function =DATE(
2. Generate a date from another date with Year, Month, Day
3. Or just enter =DAY(21) and you will get 20

Actual Results:
Entered =DAY(20) got 19 and entered =DAY(1) and got 31


Expected Results:
Expected 20 and expected 1


Reproducible: Always


User Profile Reset: No
