+Настройка NTP
+=========
+
+Данная роль настраивает часовой пояс и NTP на узлах.
+
+Requirements
+------------
+
+Тестирование приводилось на **Ubuntu 20.04 (Focal Fossa)** и **Ubuntu 22.04 (Jammy Jellyfish)**.
+
+Role Variables
+--------------
+
+Переменные не используются.
+
+Dependencies
+------------
+
+Для настройки часового пояса используется роль [community.general.timezone](https://docs.ansible.com/ansible/latest/collections/community/general/timezone_module.html), в качестве параметра принимается строка с нужным часовым поясом, например **Europe/Moscow**.
+
+Example Playbook
+----------------
+
+    - hosts: servers
+      roles:
+        - ntp-install
+
+License
+-------
