The tab bar is not visible because an empty tab bar can't be displayed:
(tab-bar-format-list tab-bar-format)
=> ((global menu-item "" ignore))
So it works fine when you change the initialization order to:
0. Evaluate
(setq tab-bar-format '(tab-bar-format-global))
1. M-x display-time-mode RET
2. M-x tab-bar-mode RET

Sorry for the late reply here. I guess what surprised me is that the
order mattered here. If you don't think this is a bug, we can close
this. Thanks.

I really have no idea how to display an empty tab-bar.
Fortunately, this is not a frequent problem, just need
to be careful not to enable tab-bar-mode when
the tab-bar is empty. But when someone will get
an idea how to handle it, this could be reopened.

Sounds good to me, and thanks for taking the time to explain things.
