I see. Do we know why is it completely wrong, when it is wrong? Do you have an example when it is completely wrong? That'll help to debug the issue.
Because if without the TZ string or with TZ=UTC0, <time.h> APIs can provide accurate UTC times, then all TZ definition helping us with is the offsets and time frame within an year.

No! I said UTC is reasonable when the TZ string is absent from the time zone file. Ie. it is the *last* resort, when no other option is *available/possible*.
