Skip-to-Position codes do not display in Podcast Addict and iTunes

Hi,

I have a problem with Skip-to-Position time codes: they do not display in the show notes pulled by Podcast Addict and iTunes (did not check it in other apps).

Funny because Podcast Addict automatically makes a time code format text into a link, but it just skips the time-code line provided in the podcast episode RSS.
So it displays nothing, not even a plain text time code.

It is the same in iTunes: no time codes, just a blank line.

Am I missing here something to make this feature work in the show notes?

Thanks,

Szabolcs
