The timestamp is obtained when the form is saved, we cannot access it.
Do you want automatic Customfields to be filled in with dayifweek automatically when creating a transaction?
If yes, you can use the Date Created script for this need, and ask chatGpt to change the code to produce DayofWeek instead of the current Date.
I don’t think you can use description for this. Instead you need to prefill your custom field using Form Defaults and add your code to output week day obtained from issue date and not timestamp ( for the reason that @Mabaega mentioned ).
