# Out-of-range eCFR dates look like bad citations

**Observed 2026-10-08.** Pipeworx `ecfr.get_section_text(title 21, section 211.22, date 2015-06-01)` returned an error: "Section 211.22 not found in title 21 as of 2015-06-01. Check the number". The same call with `date 2017-06-01` returned the full text, and with no date it returned the current text (as of 2026-10-06). 21 CFR 211.22 has been in force since 1978.

eCFR's point-in-time history only reaches back to about January 2017, so earlier dates fail — but the error tells the caller the citation is wrong.

Minor: the returned `url` points to `/current/` even for a historical date.

**How to avoid:** treat a not-found for a pre-2017 date as out-of-history, not as "no such regulation".
