Columnwidth autosizing of datetime is very slow.

After loading the values into a TListView, I wanted to automatically size the column and the column header to the size that was wide enough to display the widest element under it. Hence, I used the comctrls and used the following code snippet.

uses Commctrl;

TListView_Name.Columns[column_index].Width := LVSCW_AUTOSIZE;
TListView_Name.Columns[column_index].Width := LVSCW_AUTOSIZE_USEHEADER;

Now my columns have a datetime field and the list view is getting loaded really really really slowly when this column is autosized using the code shown above. I can see that it has to do something with the element under that column being datetime, as other columns are getting autosized properly without taking much time.

Could anyone tell me why the autosizing of the datetime column is taking so much time?

Cheers,
Gautam.
