Using Event Times and Time Zone fields in Event Templates and Email Templates

Does anyone know a way to customize the time format when using the {event-time} field in an email? The time can be customized in the event templates but apparently not in the email templates? For example, I would like to show just the date (formatted differently than the default Day Date Month Year) or just the start time.

I would also like to customize the {time-zone} field so it does not display so much non-essential and confusing information.  Although, since the time is always static in email messages, and all of our events are in the same time zone, I could just type our time zone in the text field.

Another option would be to create custom templates for each event and manually enter the times and dates to appear however I want.

Any other ideas are appreciated.

Thanks!
