How to remove "Time Zone" element "user_register_form" form using hook_form_alter I analyzed the "Create new account" page of drupal by using hook_form_alter and $form variable. as you see, #form_id value is: "user_register_form" and other elements are as following:

attributes-&gt;Array
administer_users-&gt;Array
#attached-&gt;Array
#cache-&gt;Array
account-&gt;Array
language-&gt;Array
#entity_builders-&gt;Array
#process-&gt;Array
#parents-&gt;Array
user_picture-&gt;Array
actions-&gt;Array
#form_id-&gt;user_register_form
#type-&gt;form
#action-&gt;form_action_p_pvdeGsVG5zNF_XLGPTvYSKCf43t8qZYSwcfZl2uzM
#build_id-&gt;form-78GnGyO2iwZsooojZLCOiAw9pYXyDqngJ5C0DU_EzUQ
form_build_id-&gt;Array
form_id-&gt;Array
#id-&gt;user-register-form
#method-&gt;post
#theme_wrappers-&gt;Array
#defaults_loaded-&gt;1
#tree-&gt;
#validate-&gt;Array
#submit-&gt;Array
#theme-&gt;Array
contact-&gt;Array


I want to remove "Time Zone" element of this form (user_register_form), which of this array elements should I unset to remove that element?
EDITED

As @KrishaWeb and @Kevin said:
Drupal 8 provided admin path at: admin/config/regional/settings to do it.
