Check your regulator's own form. The printable version lists the source behind every field. CSV versions have an instruction row above the headings.
Keep the completed copy and its source records. A time receipt dates those exact bytes; it does not establish that an entry is true or accepted. Save a new copy each shift.

Your device fingerprints the selected file or manifest. Dated follows an independent timestamp; Permanent follows Bitcoin anchoring.
An independent time, tied to the exact bytes.
Keep each shift’s originals and receipt. Use the existing patrol system for scanning, scheduling and missed-round alerts.
Keep the originals too. A changed or compressed copy has a different fingerprint.

Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.
A family questioned a guard's patrol after a death, and checkpoint logs showed gaps. The firm disputed what the gaps meant. The appeal court left the jury's finding against the firm in place, though one judge disagreed.
Appeal decision; judges disagreed about whether the records proved a failure to patrol and its connection to the death.

Read the report ›Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.

Read the sourceElectronic or nonqualified form alone is not a reason to deny a timestamp legal effect or admissibility. Other evidence requirements still apply. Article 41(2) addresses the qualified-timestamp presumption, and Article 42 its requirements; provider status alone is insufficient.
This describes the statutory evidence rule, not Timevolt qualification or a guarantee of admission. No claim about cross-border recognition is made here.

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.
It does not prove who walked the round, that the guard was physically at the checkpoint, that a photo shows what it claims, or that the patrol met a contract, code or fire-marshal requirement; a court or inspector decides that.
A receipt cannot prove the guard was present, a device clock was right, or a code or contract was met. Tag data is a customer claim.
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.
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.
It shows these exact files, such as your checkpoint scan export and photos, existed unchanged by a certain time. An independent timestamp authority sets that time, not your company's system.

No. It proves the record existed by a time. Where the guard was depends on your tag, beacon or other checks, which are your own data.
Local rules ask for a log with names, dates and times kept on site, and the ones we found say nothing about timestamps. Treat the receipt as an extra, and follow your fire marshal's log rules.
