PostEaseTiming carries less weight here than the video itself
Because TikTok's distribution depends heavily on how a video performs with an initial test audience rather than the exact posting hour, timing plays a smaller role here than it does on more follower-dependent platforms. A strong video posted at a mediocre time will generally still find its audience; a weak video posted at a supposedly ideal time usually won't be saved by the timing alone.
Consistency still helps, for the usual reason
Posting on a predictable schedule remains worthwhile, though not because a specific hour earns algorithmic favor. A regular habit produces more opportunities for a strong video to break out, and gives returning viewers a reason to check back.
Where your own audience is active still matters
For an account with an established, returning audience, rather than one relying entirely on the For You feed to reach new viewers, posting when that audience is likely to be active still has some value, the same as on any platform. Your own account's analytics will show that pattern better than a generic recommendation.
