Undefined index: cck_time_field_presave()
Go to CCK Time then open cck_time.module

find this:

function cck_time_field_presave($entity_type, $entity, $field, $instance, $langcode, &amp;$items)


change this: 

if (($items[0]['hour'] === '') || ($items[0]['minute'] === ''))


to this:

if ( empty($items[0]['hour']) || empty($items[0]['minute']) )


It helped solving my problem getting the same error Undefined index: cck_time_field_presave()
