            Bug ID: 116891
           Summary: Sorting of date by ascending and descending is
                    incorrect
           Product: LibreOffice
           Version: 6.0.2.1 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

Description:
I have defined a column as date column. 
When i try to sort this out by ascending or descending,the dates don't sort ,
but the behavior is rather sorted as a numerical string. 
This should not occur and with little change in algorithm or forced behavior,
dates entered in the various date format should sort by Month Jan - Dec ( 1-12)
followed by Sort order of dates ( 1-31) , followed by sort order of Year ( in
YY or YYYY )

Steps to Reproduce:
1. Create columns with various dates representing every month , few dates, few
years such as in attached list
2. Select sort area
3. Select sort by ascending and descending.

Actual Results:  
I ordered the dates by ascending. This is how it is sorted
