No we don't, it's a default-off build option.
Thanks for letting me know. I installed the attached to fix the comment.

* localtime.c (TZ_CHANGE_INTERVAL): -DDETECT_TZ_CHANGES is used only
optionally in FreeBSD builds. (Reported by Dag-Erling Smørgrav.)
Also, omit “circa 2026”, so we needn’t update the comment every year.
