      How to keep notes that hold up

      Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.

      1. Write it down straight away, on paper or in the box on a step.
      2. Put the date, time and place at the top, and who you spoke to.
      3. Use their words where you can; separate what you saw from what you were told.
      4. Sign or initial a paper note, photograph it and add the photo.
      5. Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

      Proves / Doesn’t prove

      Proves

      A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

      Doesn’t prove

      It does not prove a sign was displayed, workers were warned, the location or identity is correct, or entry was safe or permitted.

      It does not prove a sign was displayed, workers were warned, the location or identity is correct, or entry was safe or permitted.

      These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.

      Questions, answered plainly.

      Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.

      Does a time receipt make a field safe to enter?

      No. Applicable labels and worker-protection rules control entry. A receipt only dates the exact file bytes.

      What should a posting record preserve?

      Keep the applicable label, application information and actual warning records. The US rule also specifies sign placement, content, visibility and timing; a photo captures only what its image shows.

      Can an interval from another task or region be reused?

      Do not assume so. British Columbia's regulation ties entry intervals to the label and activities and provides additional conditions where labels do not specify one.
