description	Inserts a date stamp using the `date format` and `am/pm` settings
instructions	Configure the `format` variable. The following letters can be used for various parts of the date. Any other letter will be left untouched. y = four digit year m = two digit month d = two digit date h = two digit hours (AM/PM is controlled via a separate variable) n = two digit minutes s = two digit seconds Set the `am/pm` variable to true for 12 hour time or false for military time. Anywhere in a note, type `{date}` to have it replaced with your custom date stamp. open_in_new As another example, setting the format to `y-m-d [h:n:s]` returns: 2023-04-22 [11:04:43 PM]
