This module will make the date API available to other modules. Designed to provide a light but flexible assortment of functions and constants, with more functionality in additional files that are not loaded unless other modules specifically include them.

Code

function date_api_form_system_regional_settings_alter(&$form, $form_state, $form_id = 'system_date_time_settings') {
  $form['locale']['date_api_use_iso8601'] = array(
    '#type' => 'checkbox',
    '#title' => t('Use ISO-8601 week numbers'),
    '#default_value' => variable_get('date_api_use_iso8601', FALSE),
    '#description' => t('IMPORTANT! If checked, First day of week MUST be set to Monday'),
  );
  $form['#validate'][] = 'date_api_form_system_settings_validate';
  $form = system_settings_form($form);
