I also agree - I think this would be a very useful featurelet, FWIW.

Getting the documentation on this expanded a bit would help greatly
too, though.  I remember I had posted about this some time back,

interpreted in UTC or in local time, and didn't get a response.  In the
end I did my own tests to figure it out.
