Two practical details for step 2. On any Linux or macOS machine, `date -Iseconds` prints exactly the required form (`2026-09-15T07:42:10+02:00`) with the current local offset, so a shell alias that appends it to a file is a one-line logger; phone note apps usually need a shortcut or automation configured to insert the same format. When the log later goes into a spreadsheet, note that spreadsheet date cells carry no UTC offset: a parsed timestamp is converted to a bare local date-time and the offset is discarded, so a log spanning a daylight-saving change subtracts wrongly again after import. Keep the RFC 3339 strings as text and compute durations in a scripting language, or convert both endpoints to UTC in a separate column before subtracting.
