Problem importing a date with format 2016-06-17T15:21:07.891+02:00

Problem importing a date with format 2016-06-17T15:21:07.891+02:00

Hello,

I try to import a csv file with date columns in format 2016-06-17T15:21:07.891+02:00.
I used several formats but none is working.
At the end i tried to get only the date part before converting it to date with this formula :

convert_string_to_date( left("Date",10), 'yyyy-MM-dd')

but it does not work.

Please help.

Regards
