 ## 3.4.0
+- Enhancement: app-server log messages have use local timestamps instead of UTC timestamps by setting Zowe YAML configuration property `zowe.logging.timezone: local` which will take system settings into consideration for determining the right timezone to use. ([#572](https://github.com/zowe/zlux-server-framework/pull/572))
 - Bugfix: Fix TN3270 and VT terminals not appearing in the Zowe Desktop when using AT-TLS by adding a workaround for an AT-TLS CORS error between the gateway and App Server where CORS metadata has been added to the eureka registration ([#617](https://github.com/zowe/zlux-server-framework/pull/617))
 - Enhancement: Added components.app-server.enablePasswordChange parameter to the Zowe YAML configuration file for controlling visibility of the 'Change Password' option in the Zowe Desktop Personalization Panel. This value defaults to true, the prior behavior, when not present in the YAML. ([#616](https://github.com/zowe/zlux-server-framework/pull/616))
