Bug description

I am using the DATE_FORMAT_IN_EMAIL_SUBJECT feature with an hourly scheduled report using a token to display the current datetime i.e. Propane Hourly Report %c. The substitution works the title of the email sent is "[Report] Propane Hourly Report Wed Oct 29 09:32:01 2025". However the datetime substitution is for the datetime the schedule was saved and never changes for each new email sent.

Should the substitution not be evaluated with each new hourly email sent ?
