Hello, you can try below process :

Translations --> Language --> Edit

Replace time format : %H:%M:%S to %I:%M:%S %p

import following:

from odoo.tools import float_is_zero, float_compare, DEFAULT_SERVER_DATETIME_FORMAT

define in your function in place of time format DEFAULT_SERVER_DATETIME_FORMAT i hope it helps you.


For Reports and XML(QWeb) you can do it this way:

<span t-esc="datetime.datetime.strptime(object.date, '%Y-%m-%d %H:%M:%S').strftime('%d/%m/%Y %I:%M:%S %p')"/>

Hope it helps
