Expected behavior

Timezone gets set to UTC

Actual behavior

Timezone remains local time

How to reproduce?

• Set timezone to UTC in _config.yml
• Change date_format to date_format: YYYY-MM-DDTHH:mm:ss.SSSZ
• Write a post using a timezone
• When I load it up, the timezone is -0700 for me as I am currently in PDT, expect Z or +0000
