Specifying the default time zone in `feed.config.date`

[trustin]

Hello! :wave: It'd be nice if there a way to specify the time zone of the selected datetime text. rsspls currently assume UTC, which is not always correct.

So this would be for when the actual text does not contain a time zone I assume?

I imagine an optional field on the date table might work?

[feed.config.date]
selector = "time"
type = "DateTime"
format = "[day padding:none]/[month padding:none]/[year] [hour repr:24]:[minute]"
timezone = "UTC+10"
