Use Timestamp converter only for the explicit D03 and D05 instants. Paste each original +08:00 string and click Reverse conversion for Unix seconds: D03=1791680400, D05=1791649800. Download TXT, then paste seconds and use Forward conversion; expect 2026-10-11T01:00:00.000Z and 2026-10-10T16:30:00.000Z. wrong-d05.txt retains 00:30 but replaces the offset with Z; its seconds are 28,800 later than correct D05. Recover from the original +08:00 string. D01 stays a calendar date without midnight; D02 retains both candidates; D04 awaits zone evidence. A parser may accept ambiguous strings without verifying meaning. Each TXT contains one conversion, not a complete source ledger.
