Created attachment 108081 [details] Cutdown screenshot: Date and time config module with wrong TZ name shown. Reporting that the timezone shown for Europe/London in the list of selectable timezones is given incorrectly. This is a minor error in text; Europe/London is Greenwich Mean Time or GMT. In the list, it is shown as LMT. Simply a typo. I've attached a screenshot of where the error is visible. Thanks!
GMT roughly matches UTC. We are in GMT in winter, BST in summer. LMT stands for Local Mean Time which is the time zone in wherever you currently are. Any applied timezone will append (LMT).
As David mentioned, this is the correct functionality.
