Timezone/timestamp issue

There was a mention here of a fix for those of us having strange timestamp issues (new tweets show 7 hours ago, then hours go down). I see in the code the fix was implemented but I’m still having issues. One thing that I’ve been able to do to fix this: Going to Settings -> General, and changing my timezone to UTC. If I use my city name, or UTC-7, etc., I still have an issue. This definitely doesn’t seem to affect all users, and I used a widget from another developer and had the same exact issue. At least this pins it down on WordPress settings and not php/server/Twitter time (in my opinion). Is there some code that can be added (I would volunteer to update my site to try it out) to fix this? Maybe a settings box programmed to use UTC in lieu of whatever WordPress timezone settings are? It would seem that since changing WordPress time fixes this for me, the widget is using that time in some fashion. Thanks! https://wordpress.org/plugins/wp-twitter-feeds/
