Time-Series Gap Analyzer

Audit timestamp continuity without uploading data or filling missing observations.

Interpretation notice: sorting is analytical only; original row order is preserved in reports. Time-zone-free timestamps require an explicit assumption. Local civil times around daylight-saving transitions can be ambiguous or nonexistent. This tool reports, but never imputes, missing rows.
