Digital Time Stamp Signature for SignNow
Award-winning eSignature solution
What a digital time stamp signature is
A digital time stamp signature is an electronic signature record that captures when a person signed a document and preserves that event in a verifiable audit trail. In SignNow, the signed file, timestamp, and signing history stay linked so teams can review who acted, when they acted, and whether the document changed afterward. In the U.S., that evidence supports ESIGN and UETA workflows when the signer intended to sign and the record is retained correctly.
Why timestamped signatures matter
A digital time stamp signature helps show when a document was signed, preserved, and reviewed. Under ESIGN and UETA, that record can support enforceability and evidence handling in U.S. business transactions when signer intent, attribution, and retention are documented properly.
How a digital time stamp signature works
A digital time stamp signature links the signer’s action to a trusted time record, then preserves the document history for later review.
Open document: The signer opens the document and reviews the record before signing. Capture timestamp: The platform captures the signer action and records a trusted timestamp. Hash and seal: The file is hashed and sealed against later changes. Store evidence: The completed record is stored with an auditable trail for review.

Recommended signing setup
Use a simple configuration that records identity, timestamps, and retention rules without adding unnecessary process steps.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP with ID verification |
| Signature type | SES with tamper-evident record |
| Audit trail | Enable full time-stamped logging |
| Document retention | Match the governing rule |
| Encryption | TLS 1.2/1.3 and AES-256 |
Record-keeping practices that hold up
Use a retention plan that matches the document type, preserve audit evidence, and archive records in a way that supports later review.
Keep the full record set
Use secure archival storage
Export evidence packages
Align deletion with policy
Platform requirements for digital signing
Digital time stamp signature workflows run in current browsers and mobile apps, with secure TLS-based connections and standard desktop or mobile operating systems.
Desktop browsers Chrome, Firefox, Safari, and Edge on Windows or macOS. Mobile support iOS and Android mobile apps for signing on the move. Connection security TLS 1.2 or later, with secure browser access.
For regulated deployments, organizations often combine managed Windows or macOS devices, mobile app access on iOS or Android, and controlled account provisioning. API access, SSO, and certificate-based configurations can help larger teams keep access and record handling consistent across departments.
Who uses digital time stamp signatures
Real estate
Real estate teams use timestamped signatures for leases, disclosures, and rental applications that need a clear signing record.
Healthcare
Healthcare teams use timestamped signatures for consent forms, patient intake, and HIPAA-covered records with audit requirements.
Business types that benefit most
Different business sizes use timestamped signatures for faster document control, cleaner evidence, and more predictable retention.
Solo practitioners often use digital time stamp signature workflows for contracts, engagement letters, and client intake records that need fast turnaround and simple archiving without separate paper handling. Mid-market legal and operations teams use it for role-based approvals, internal routing, and reusable document templates where audit history and consistent signing order matter across departments. Enterprise compliance and finance teams rely on it for controlled execution of recurring records, retention rules, and reviewable evidence across distributed locations and regulated business processes.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
How teams manage access and roles
Centralized administrators assign roles, manage templates, and control who can send or sign from shared workflows. SignNow account controls help keep permissions aligned with internal policy while supporting delegated sending, reusable folders, and access limits for sensitive records. Document owners can share templates with recurring approval teams and keep the signing process consistent across departments. Delegated sending helps managers distribute work without giving every user the same level of access or visibility.
Privacy and disclosure risks
Signed documents can expose PHI, PII, or financial data if attachments are shared too broadly. Consent capture matters when records are delivered or stored electronically, especially for regulated or consumer-facing workflows. Access control mistakes can let unauthorized users view or download signed files and audit records. If retention rules are unclear, privacy reviews and deletion requests become harder to manage consistently.
Risks of getting timestamping wrong
Weak audit trail
No timestamp proof
Audit gaps
Untrusted evidence
Retention schedule for signed records
Use the record type to determine the retention rule. Keep the signed document, the audit trail, and any exportable evidence together when a regulation applies.

Questions about signing records
These answers cover plan limits, compliance requirements, and evidence handling for timestamped signatures in SignNow.
SignNow supports audit trails, timestamps, templates, mobile apps, and ESIGN and UETA workflows. If an audit trail looks incomplete, confirm the document was signed in a live session and that completion records were not exported from an earlier draft. Paid plans include unlimited users, and business tiers can support more advanced workflow needs.
For HIPAA-covered workflows, SignNow can support compliance when you also have a BAA in place, use access controls, and keep signed records for 6 years under 45 CFR 164.530(j)(2). HIPAA itself does not require one e-signature method, but it does require safeguards for PHI.
If signer identity needs stronger proof, use SMS OTP or ID verification rather than a weaker email-only flow. The authentication method should match the transaction risk, and the record should show who signed, when they signed, and what they signed.
The Business plan starts at $8/user/month, and Business Premium adds bulk send and kiosk mode. If you need SSO, full API access, or other deployment controls, the Site License and Enterprise options are the better fit.
A digital time stamp signature is generally supportable under ESIGN and UETA for U.S. business records, but wills and certain court orders are excluded. If the document type requires notarization or a wet-ink signature, electronic execution may not be enough.
Export the completed PDF and audit trail together so reviewers can verify timestamps, signer actions, and document integrity later. If a PDF opens without its record history, check whether the audit log was separated from the signed file during download or storage.
