+Feature: SystemTimeManager runs only one instance
+
+  Scenario: SystemTimeManager exits if another instance is invoked
+    Given the SystemTimeManager is not already running
+    When the SystemTimeManager binary is invoked
+    Then the SystemTimeManager should be started
+    And when the SystemTimeManager is attempted to be started again
+    Then the SystemTimeManager should not start another instance
