Clock in tab bar?

I use `tab-bar-mode` a lot. I also have a lot of stuff on my mode-line. I used to use Emacs such that I could see the clock on my OS, but now I want to try using Emacs entirely full-screen; problem is, I don't have a clock any more. I used to have it on the mode-line, but I didn't like how the time was replicated *everywhere*, and it was taking up space that I wanted for other things. Is there a way to put a clock, say, in the right side of the tab-bar? This is a little line of space that is almost *never* in use, so it'd be perfect. **Update**: Here's a hack that I *don't* recommend, but it was kinda fun to figure out: it uses a posframe and a timer to get it to display: https://paste.sr.ht/~ashton314/4d490af6b4c6ae2f00012c8d807383001b242f1e There are some better suggestions in the comments, which I'll probably be using. :) **2nd Update**: Thanks to u/karthink, I've found a solution that works perfectly: ```lisp (add-to-list 'tab-bar-format 'tab-bar-format-align-right 'append) (add-to-list 'tab-bar-format 'tab-bar-format-global 'append) (setq display-time-format "%a %e %b %T") (setq display-time-interval 1) (display-time-mode) ```

New to Emacs haven't used the tab bar. `C-h v` showed me `tab-bar-format` which you could set to something like `(setf tab-bar-format '(tab-bar-format-history tab-bar-format-tabs tab-bar-separator tab-bar-format-add-tab current-time-string))` Doesn't appear to refresh often though

The built-in solution requires Emacs 28. Add `tab-bar-format-global` to `tab-bar-format`: (add-to-list 'tab-bar-format 'tab-bar-format-global 'append) Now turning on `display-time-mode` should display it in the tab bar instead of the mode-line. This works for any text that is otherwise displayed in the `global-mode-string`.

Hey that works pretty well! Is there a way to get the time to move all the way over to the right?

Add `tab-bar-format-align-right` at the desired position to `tab-bar-format`. See the doc for more details.

I just found that in the docstring before reading this. :) I've updated my original post with the final solution. Thank you so much for your help in pointing me to the right place!

Not in the tab bar, but I found Symon a while back. It's abandoned, but it displays monitors in the echo area. I picked it up, rewrote a bunch, and renamed it [lemon](https://gitlab.com/ieure/lemon). I use it every day, give it a shot if you like. It's not perfect, but works alright for me, and the other things I've tried have been worse in some way or another.

This is a very nice recommendation. I'll have to give this a look. Thanks!
