Your starting prompt.
Compare [current daily report] with totals recalculated from [event timestamps] in [business timezone] using [cutoff rule]. Inspect daylight saving transitions, midnight boundaries and timestamps without offsets. Show which records move between reporting dates and explain the variance. Propose a documented timestamp normalization Model, but keep unresolved timezone assumptions visible instead of silently assigning a local timezone.
Copy this starting point, then replace the placeholders with your own inputs.
Method and review
Keep the assumptions visible.
Profile keys, row counts, types, missing values and join cardinality. Retain source lineage and concrete exception records so a correction can be checked.
For this task, check
Offset free timestamps cannot always be converted accurately without source timezone evidence.

Before you begin
- Bring exports you are allowed to upload, or data your Workspace can already query.
- Choose the reporting period and agree what each record represents.
Work with permitted files or queryable data. Verify the result against the original records.
