The “New journal here” button is defined here:
https://tiddlywiki.com/#%24%3A%2Fcore%2Fui%2FButtons%2Fnew-journal-here
If you examine that tiddler, you will find that the button actions are defined “inline” inside the $button definition using these three lines:
<$wikify name="journalTitle" text="""<$macrocall $name="now" format=<<journalTitleTemplate>>/>""">
<$action-sendmessage $message="tm-new-tiddler" title=<<journalTitle>> tags=<<journalButtonTags>>/>
...
</$wikify>
The problem arises because the above code calculates the journalTitle value (using the now macro) when the button is first rendered, rather than when the button is actually clicked upon.
You can correct this by moving these three lines from the journalButton() definition into a separate macro definition, like this:
\define newJournalHereActions()
<$wikify name="journalTitle" text="""<$macrocall $name="now" format=<<journalTitleTemplate>>/>""">
<$action-sendmessage $message="tm-new-tiddler" title=<<journalTitle>> tags=<<journalButtonTags>>/>
</$wikify>
\end
and then, in the journalButton() macro definition, add an actions=... parameter to the $button definition to invoke <<newJournalHereActions>>, like this:
<$button tooltip={{$:/language/Buttons/NewJournalHere/Hint}}
aria-label={{$:/language/Buttons/NewJournalHere/Caption}}
class=<<tv-config-toolbar-class>>
actions=<<newJournalHereActions>>>
The result is that the $wikify widget that computes the target journal title value will be performed when the $button is pressed, rather than when the $button is initially rendered, thus producing a unique datetime value each time.
This should probably be reported on GitHub as a bug to be fixed.
