How to print field stored as time in HH:MM AM/PM format in template

I have a field say start_time stored as time in the doctype field.

I would like to print the start_time in HH:MM AM/PM format eg. 0:23:00 as 11:00 PM
{{ frappe.format(start_time,{'fieldtype': 'Time'}) }} is not really helpful. strftime also does not seem to work

This is currently not possible on frappe unfortunately.
