Fatal error: Call to undefined function date_iso2array()

Same here.

The issue seems to rest in line 95 of content.inc:

include_once(drupal_get_path('module', 'date') .'/date.inc');

In the current 5.x version of the date module, date.inc no longer exists. Date functions are now split into a set of *.inc files.

Try this...

Remove your date fields.
Uninstall the 2.x date modules.
Install the 1.8 date module.
Add your date fields back with the same settings.
Run your import.
Upgrade to date 2.x if you wish. I haven't gone this far yet, but I was able to import using Date version 1.8.

Hi. I have a problem with Node import and Date 5.x-2.0-rc:

    * warning: include_once(modules/date/date/date_timezones.inc) [function.include-once]: failed to open stream: No such file or directory in /var/www/cfcf/modules/node_import/supported/event.inc on line 8.
    * warning: include_once() [function.include]: Failed opening 'modules/date/date/date_timezones.inc' for inclusion (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/cfcf/modules/node_import/supported/event.inc on line 8.

See #227681: Date 2 API breaks node imports with dates

I have run into the similar problem when i applied date 2.x now when i reverted back to 1.8x the imports have started.
I am able to import all fields but the date value.
I have tried all date formats including the iso yyyy-mm-dd
