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