I seem to be unable to find the tutorial or info on how to change the date format of a newly created Tiddler.(The date under the Title) The default gives me: "4th December 2019 at 8:40am"I want: "2019 12 04 0840 [UTC]"
<$view field="modified" format="date" template={{$:/language/Tiddler/DateFormat}}/>
DDth MMM YYYY at hh12:0mmam
[UTC]YYYY 0MM 0DD 0hh0mm [UTC]
The date under the title is the modified date and Eric has shown you how to change how it appears in the subtitle.
However you can use the view widget to display and date field however you want.
