comment_end_date
A FULL UTC INSTANT, not a calendar date, despite the column name: '2026-08-29T03:59:59Z' is 11:59:59 PM EASTERN on 2026-08-28. Federal comment periods close at 11:59:59 PM Eastern, so the UTC calendar date is ONE DAY LATER than the official deadline on every end-of-day close — 444,689 of the 444,690 populated rows (measured 2026-09-06). Convert to America/New_York before presenting a deadline, and compare with julianday(comment_end_date) > julianday('now'): a plain > datetime('now') is a TEXT comparison between two different formats and keeps already-closed dockets matching for up to ~20 hours. The sibling column on open_comments.documents WAS corrected to an Eastern calendar date (queue #498); this one is unchanged and still an instant — the two databases do not agree on grain. (queue #644)
comment_start_date
A FULL UTC INSTANT, not a calendar date, despite the column name — same grain as comment_end_date on this table. Convert to America/New_York before presenting it. (queue #644)
