Now keep it safe: three things
  1. Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
  2. Save this receipt to your camera roll.

    Keep the receipt file too. The image is a handy copy; checking needs the file.

  3. Email it to yourself.Email it to myself

    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.

    Keep the board or training program’s official records and confirmations. A venue code or receipt does not establish attendance.

    Keep the originals too. A changed or compressed copy has a different fingerprint.

    Keep records of which hours apprentices worked

    A firm wanted lower rates used for apprentice hours but had kept no records of who those workers were. The court used an expert's hour estimates instead. It found linked firms shared the union contractor's duties to pay.

    Related: pay rates and worker timecards

    Workers said a building firm split their hours into lower paid training that did not match the work. The state counted the hours at the skilled rate. The appeal court kept a three year ban on public jobs for breaking wage rules on purpose.

    What courts, schemes and regulators say.

    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.

    Silent · US federal (registered apprenticeship)

    US Department of Labor, Office of Apprenticeship

    29 CFR 29.5 apprenticeship standards: time-based programs measure skill by completion of at least 2,000 hours of on-the-job learning tracked against a work process schedule; programs must keep appropriate progress records, ensure adequate supervision on the job, and give a transfer transcript of related instruction and on-the-job learning when an apprentice transfers.

    The rule requires the sponsor to keep records and does not say anything about timestamps, digital signatures or independent dating. Retention period not specified in the section as retrieved. Sponsor holds the official record, so a time receipt is supporting material only.

    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 who worked the hours, that the apprentice was at the job site, that the journeyperson really supervised, that the training was delivered, or that a board will credit the hours.

    This cannot establish hours worked, supervision, training delivered or credit granted.

    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.

    How many on-the-job hours does a registered apprenticeship need?

    Time-based federal standards call for at least 2,000 hours of on-the-job learning, tracked against a work process schedule. Trades and states set their own totals, often much higher, so check your program.

    Who keeps the official record of my hours?

    The program sponsor must keep the progress records. Keep your own copy as well, because a transferring apprentice is owed a transcript but only the sponsor can issue it.

    Context for this answer
    Does a time receipt replace my journeyperson's signature?

    No. The signature is the sign-off your program wants. A time receipt shows when the signed file existed, in exactly that form.

    Can a time receipt prove I was at the job site?

    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.

    Do you see my timesheets or photos?

    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.

    Will my licensing board or program accept it?

    Unknown for any given board. Boards and sponsors decide what they accept, and most require their own form. Use the receipt as supporting evidence of when your records were made.

    What if I edit the log after the receipt?

    Any change, even one character, gives a different fingerprint, so the old receipt will not match the edited file. Keep the original file you dated.

    What does it cost?

    See the Pricing page for current US-dollar plans and allowances. Fast is paused. Purchases open when receipts open.
