Timestamp Digital Signature for Secure Signing
Award-winning eSignature solution
What a timestamp digital signature does
A timestamp digital signature is a digital signature that records the exact time a document was signed and ties that time to the signed file. In practice, the system captures signer identity, the signing event, and a secure timestamp, then seals the record so later changes are detectable. For U.S. transactions, this helps show when an agreement was executed, supports auditability, and strengthens evidence that the document has not been altered after signing.
Why timestamping matters for enforceability
Timestamped signatures help document when consent was given, reduce disputes over signing order, and support record integrity. Under ESIGN and UETA, electronic signatures can be enforceable when attribution, intent, and record retention are shown, and a reliable timestamp strengthens that proof.
Common timestamping pitfalls
Missing or weak timestamps can make it harder to prove when a signer acted, especially in multi-party agreements and regulated records. Poor identity checks can weaken attribution, which creates disputes over whether the correct person actually signed the document. Unsigned or incomplete audit trails can leave gaps in the signing history, reducing evidentiary value in court or compliance reviews. Improper retention or export settings can make it difficult to retrieve signed records when legal, audit, or regulatory requests arrive.
Where timestamped signatures fit
Real estate
Real estate teams use timestamped signatures for leases, rental applications, and closing packets that need clear execution timing.
Healthcare
Healthcare organizations use timestamped signatures for consent forms, intake records, and HIPAA-related authorizations that require traceable signing events.
People who rely on signing timestamps
A director of NetSuite operations at a large manufacturer may need timestamped signatures on purchase approvals, vendor agreements, and internal controls. In Xerox’s customer story, integration with NetSuite helped route the right documents in the right formats, which matters when approval timing and system records must stay aligned. A founder managing property transactions can use timestamped signatures for lease packets, disclosures, and mobile signing workflows. In Martin Properties’ customer story, online execution with built-in security and mobile access helped keep documents moving while preserving a clear record of when each party signed.

Key features of timestamped signatures
Timestamped signatures combine identity, timing, and integrity controls so teams can document execution with more confidence and less manual follow-up.
Secure timestamp
Records the signing moment and preserves it with the signed file, which helps establish when consent occurred and supports later review of the transaction history.
Tamper evidence
Creates a tamper-evident record that makes post-signing changes easier to detect, which supports document integrity and non-repudiation.
Audit history
Captures signer activity in a traceable sequence, helping teams review who acted, when they acted, and what changed during the process.
Signing order
Supports multi-party workflows where signing order matters, so each signature event can be tied to a clear point in time.
Evidence retrieval
Helps legal and compliance teams retrieve evidence quickly when they need to confirm execution timing, identity, or document status.
Cross-device use
Works across desktop and mobile signing flows, which keeps timestamped execution available when people sign in the office or on the go.
How timestamping works step by step
The signing flow records identity, time, and document integrity in sequence, then preserves the evidence for later verification.
Capture event: The platform records the signer, the action, and the exact time. Bind time: It attaches the timestamp to the signed document record. Seal record: It applies cryptographic protection to detect later changes. Log evidence: It stores the audit history for later review or export.
Quick setup for timestamped signing
Use a short setup sequence to prepare the document, define signers, and send a timestamped signing request.
Prepare file:
Upload the document you want signed. Set recipients:
Add signers and assign the signing order. Configure controls:
Choose authentication and timestamp options. Track signing:
Send the document and monitor completion.
Recommended workflow settings
A clear setup helps preserve identity evidence, signing time, and record integrity across regulated and routine document workflows.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP for higher assurance |
| Signature type | Digital signature with audit trail |
| Audit trail | Enable immutable event logging |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Browser and device support
Timestamped signing works in modern browsers and mobile environments that support secure web sessions, document viewing, and electronic consent.
Browser support Chrome, Firefox, Safari, and Edge Operating systems Windows 11, macOS, iOS, Android Mobile devices iPhone, iPad, and Android phones
For regulated deployments, managed devices, current browser versions, and stable network access help preserve session integrity, audit logging, and document retrieval. Teams that need API access, SSO provisioning, or long-term validation should also confirm account permissions, storage policies, and certificate handling before rollout.

Real-world signing workflows
Customer stories show how timestamped signing fits operational, legal, and mobile workflows across different industries.
Enterprise operations
A NetSuite operations leader needed signatures tied to system records and approval timing.
- Xerox used signNow with NetSuite integration.
- Right documents, right formats, right timing.
The workflow helped align approvals with business systems, which reduced manual routing and kept execution records easier to review across departments.
Real estate
A property founder needed mobile execution with clear signing records for documents sent outside the office.
- Martin Properties signed online and on mobile.
- Built-in security supported document turnaround.
The process kept lease and transaction documents moving while preserving a clear execution history, which is useful when timing, consent, and record retention all matter.
Practical ways to use timestamps well
Good timestamp practices focus on identity, sequence, retention, and retrieval, not just the moment a signature appears on screen.

FAQ about timestamped signatures
These answers focus on signNow features, plan details, and U.S. compliance standards that affect signing records and audit evidence.
signNow includes audit trails and timestamped records on paid plans, while the Business plan starts at $8/user/mo billed annually. For HIPAA workflows, a BAA is required, and the record set should include signer identity, time, and document history.
If a document shows the wrong signing time, check the sender’s time zone, device clock, and account settings. signNow audit trails record event times, and exported records should match the system log. For regulated records, keep the signed file and audit trail together.
If a signer cannot complete the process on mobile, confirm browser support or use the signNow mobile app on iOS or Android. ESIGN and UETA allow mobile signing when intent, attribution, and record retention are preserved.
If you need stronger identity proof, use advanced authentication instead of simple email access. signNow supports workflows that can be paired with stronger controls, and high-risk records often rely on two-factor authentication or ID verification under regulated policies.
If a completed file is hard to retrieve, check document retention settings and export permissions. signNow paid plans include audit trails, templates, and unlimited users, while HIPAA records should be retained for 6 years under 45 CFR 164.530(j)(2).
If a compliance review asks whether the signature is enforceable, the key standards are ESIGN and UETA in the U.S. A reliable timestamp, clear signer attribution, and a tamper-evident audit trail help support admissibility and record integrity.
