Theme Day/Night Time Setting

My feature request has to do with the theme settings.

A bit of background.

I write sometimes starting at 4 pm. So, around then I like the Sorbet.

However, sometimes I write starting around 9 pm or even later, (time right now 3:20ish am). So, around now I like the Cauldron theme, dark equals me to start getting tired.

If we could get a theme timer to force a change between two themes (or more) of our choosing, I would love this site even more.

At the same time the timer would act as a notice to the writer of what time it is, when the theme changes at the time we want.

For let’s face it…. sometimes we can get sooo into writing we lost track of time……(This is me).

Thank you for your consideration.
