Date and timestamp with kibana version 4.3.0

Hello
on my .scv file there is a column with old date (representing 2 years)
Field name is "begin" (date) on my .scv file
On the settings page when i was declaring my new index there was the @timestamp or date
that was the proposed choices
i selected date and everything was right for me :slight_smile:
but with the last kibana version there is just the @timestamp
so my 2 years old history is out :frowning:
there's just @timestamp :frowning:
All my dates are at the minutes... !
how can i correct this ?
