Electronic Signature Timestamp for SignNow
Award-winning eSignature solution
What an electronic signature timestamp does
An electronic signature timestamp records the exact date and time a document was signed, then links that moment to the signer’s actions and document version. In practice, it helps prove when a signature occurred, supports auditability, and strengthens legal evidence under U.S. electronic signature rules. SignNow stores timestamped audit data with signer activity, document history, and tamper-evident records so teams can review the sequence of events later.
Why signing time matters
Electronic signature timestamp helps show when a document was executed, which supports contract administration, evidence review, and retention practices. Under ESIGN and UETA, electronic signatures can be enforceable when they show intent and attribution, and a reliable timestamp strengthens that record without changing the legal framework itself.
Key features that preserve signing time
Timestamped eSignature workflows depend on traceable events, secure history, and controlled access, especially when legal proof and internal recordkeeping both matter.
Exact timing
Each signing event captures a reliable time marker that helps teams prove when consent, approval, or execution occurred and ties that moment to the signed file version.
Audit history
Document history shows signer actions in sequence, which supports review teams that need a clear chain of events during audits or disputes.
Tamper evidence
Tamper-evident records help reveal changes after signing, so the final file stays traceable even if someone tries to alter it later.
Multi-signer records
Multiple signer scenarios preserve separate events for each participant, which matters when different approvers sign at different times or in different orders.
Mobile signing
Mobile signing keeps timestamps intact on phone or tablet workflows, which helps distributed teams finish documents without delaying the record.
Exportable history
Exportable histories let administrators review or share signed-document details when retention, litigation support, or internal control review is required.

How timestamped signing works
A timestamped signing flow captures identity, signing time, and document integrity in sequence so the final record is easier to verify later.
Authenticate signer: Signer identity and document access are verified before the signature event. Capture timestamp: The system records the exact signing time in the audit trail. Hash the file: A document hash locks the signed version against later changes. Seal and store: The record is sealed for later review and evidence export.

Document types that carry timestamps
Contracts and NDAs
Contracts and NDAs often need timestamped audit records for legal teams and sales operations.
Operational records
HR forms, invoices, and consent forms benefit from signed timestamps for payroll, finance, and patient workflows.
Business types that rely on timestamps
Different organizations use timestamped signatures for different records, but the legal need is the same: clear proof of signing time and document integrity.
Solo law practices use timestamped audit records to show exactly when clients signed retainers, NDAs, and settlement documents, which helps when deadlines, privilege, or dispute timing matters. Healthcare groups use timestamped signatures on consent forms, intake packets, and HIPAA-related acknowledgments so compliance teams can track who signed, when they signed, and which version they saw. Enterprise operations teams use timestamped approvals for contracts, policy acknowledgments, and internal authorizations across distributed departments, where role-based workflows and archived records matter more than a single signing event.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.
Recommended setup for timestamped records
A clear setup keeps the signing record defensible, readable, and easier to retain under U.S. compliance rules.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP or ID verification |
| Signature type | SES with audit trail |
| Audit trail | Enabled for every transaction |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Browser and device support
SignNow works in supported browsers and mobile apps over secure TLS connections, so teams can sign on desktop or mobile without special hardware.
Browser support Chrome, Firefox, Safari, Edge Operating systems Windows, macOS, iOS, Android Access options TLS 1.2/1.3 and signNow apps
Admin-managed deployments may also use mobile apps, role-based access, and retention controls for regulated workflows. For healthcare, financial services, and enterprise use, organizations should align device policy, authentication strength, and archive settings with internal security requirements and applicable rules such as HIPAA or 21 CFR Part 11.

Sending and signing methods
- Use the web app for desktop review, internal routing, and documents that need a full browser-based signing session with easy access to templates and audit history.
- Use the mobile app when approvers or clients need to sign from a phone while traveling, at a job site, or away from a workstation.
- Use kiosk mode for in-person capture at reception desks, counters, or events where multiple people sign on the same managed device.
- Use shareable signing links when recipients should access the document directly without a long email thread or manual account setup.

FAQ and troubleshooting
These answers focus on timestamped signing records, compliance needs, and the signNow plan features that support them in real workflows.
SignNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps, while Business Premium adds bulk send and kiosk mode. For timestamp evidence, the audit trail records each event in sequence, which supports ESIGN, UETA, and, where applicable, HIPAA documentation practices.
HIPAA workflows need a BAA, unique user identification, audit controls, and integrity protections. SignNow’s compliance features support those needs, but healthcare teams should confirm the BAA is signed and the document retention process still meets 45 CFR 164.530(j)(2).
21 CFR Part 11 workflows need secure audit trails, validated systems, and two-factor authentication. SignNow can support timestamped records and controlled access, but regulated life sciences teams should validate their own process and confirm the required Part 11 controls before production use.
If mobile signing is the issue, SignNow mobile apps support signing on iOS and Android, and the signed record still keeps its audit trail. A desktop browser session is not required, but organizations should verify device policy and authentication rules before field use.
For bulk sends, Business Premium adds bulk send and kiosk mode, while the Business plan focuses on core eSignature workflows. If you need high-volume distribution, check whether your plan includes the sending method and whether each completed file still stores the full history.
If a document must be retained for legal review, export the completed file and its audit trail immediately after signing. SignNow keeps event history tied to the transaction, but the retention period is your organization’s responsibility under the document class and governing rule.
