Text-file exports can carry RFC 1123 dates ("Fri, 14 Feb 2025 15:20:09 GMT"),
which sort on the weekday name and fall outside --fromDate/--toDate
comparisons. PostDates.Normalize converts them on every PostDate write path
(AddPost, UpsertPostFromTextFile, UpdatePostContentFields).
normalize-postdate.sql fixes the 4 existing rows.

-- normalize-postdate.sql
|
|
-- Rewrites Posts.PostDate values held in RFC 1123 form ("Fri, 14 Feb 2025 15:20:09 GMT")
|
|
-- into the column's canonical "yyyy-MM-dd HH:mm:ss GMT" (the Tumblr API's own format).
|
|
--
|
|
-- As of 2026-09-21 this matched 4 rows, all zombaee, from one text-file import. As text
|
|
-- they sort on the weekday name and never satisfy --fromDate / --toDate comparisons.
|
|
-- New writes are normalized in code by PostDates.Normalize, so this is a one-off.
|
|
--
|
|
-- Only PostDate changes. DateModified is left alone: the post content did not change.
|
|
--
|
|
-- HOW TO RUN: back up TL.db, then from the URLNotesGrabberCORE project folder:
|
|
-- sqlite3 TL.db < ../normalize-postdate.sql
