Lets test it using VATA TV channel
Here is screenshot from SMTube that use Tonvid.com website parsing, so all video publishing dates shown correctly.
And here is screenshot from RSS Guard that use feed from HookRSSTube, as you can see there no correct dates for each video publishing date. So, its impossible sort videos list correctly to publishing date.
When I read feed of any project commits history on Github, each entry has own date according commit date created - look on "Created on" column on this screenshot from RSS Guard.
Am I missing something?
I think the issue is now fixed in production, caching complexities notwithstanding.
