=head2 connect_call_datetime_setup
Used as:
on_connect_call => 'datetime_setup'
In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the C<DATE> and
C<DATETIME> formats.
Sets the following environment variables:
GL_DATE="%m/%d/%Y"
GL_DATETIME="%Y-%m-%d %H:%M:%S%F5"
The C<DBDATE> and C<DBCENTURY> environment variables are cleared.
B<NOTE:> setting the C<GL_DATE> environment variable seems to have no effect
after the process has started, so the default format is used. The C<GL_DATETIME>
setting does take effect however.
The C<DATETIME> data type supports up to 5 digits after the decimal point for
second precision, depending on how you have declared your column. The full
possible precision is used.
The column declaration for a C<DATETIME> with maximum precision is:
column_name DATETIME YEAR TO FRACTION(5)
The C<DATE> data type stores the date portion only, and it B<MUST> be declared
with:
data_type => 'date'
in your Result class.
You will need the L<DateTime::Format::Strptime> module for inflation to work.
