To display Summer Time tokens, you can specify the font to use to display a specific symbol to identify each event and the label that it should have in specific diaries.

By default, the Display label and symbol everyday option is set to false, which means that the label and symbols selected above will only appear on the dates when summer time starts and ends. If that option is set to true, then the label and symbol corresponding to the status of summer time will be displayed on every day.
