Time Stamp Server


Time Stamp Server

Secure and accurate time stamping for digital records

FIPS 140-2    Common Criteria

Time Stamp Server from Thales e-Security is a turnkey, network-attached appliance that keeps accurate time and creates secure time stamps to record creation time, filing time, or the timing of other events associated with electronic records and applications. By deploying a highly accurate and tamper-resistant electronic time stamping solution, organizations can verify the accuracy of time stamps used for digital records and improve the integrity and auditability of a broad range of critical processes. Ideal for organizations that need electronic document signing with proof of time for legal and compliance purposes, Time Stamp Server’s other common applications include financial transactions, lotteries and gaming, security logs, approval workflows, long-term archives, electronic lab books, and code signing. 

Unlike software-based systems in which administrators can easily manipulate time values, Time Stamp Server protects time stamping keys in independently certified, tamper-resistant hardware.

In addition, Time Stamp Server offers superior time accuracy and auditability, delivering secure time traceability to national atomic clocks and Universal Coordinated time (UTC) if required. Time Stamp Server was the first solution of its kind to support Microsoft Authenticode, the code-signing standard for Windows platforms. The product’s time stamping component is validated to FIPS 140-2 Level 3 and Common Criteria EAL4+.

Benefits of Time Stamp Server

  • Performs highly accurate time stamping for PKI-enabled applications, electronic records, and code signing—transforming electronic records into strong evidence.
  • Delivers superior time accuracy and auditability, with time stamps auditable to UTC.
  • Protects the electronic time stamping process and keys through independently certified, tamper-resistant hardware.
  • Integrates easily with business applications to time stamp digitally signed documents (e.g. PDFs), application code, or other electronic records.


Time Stamp Server Features

Security Features 

  • A tamper-proof network-attached hardware device isolates and protects critical time stamping keys from manipulation, providing trusted time stamps for a broad range of security and business applications.
  • A highly accurate, standards-based device that is auditable to UTC delivers secure time traceability.

Operational Features

  • Standard interfaces support integration with a wide range of applications.
  • The ability to operate the device remotely reduces operational costs.

Time Stamp Server Options and Accessories


Time Source Master Clock

Time Source Master Clock is a companion product to Time Stamp Server. This network-attached time appliance enables consistent, accurate, and auditable time stamping by securely distributing accurate time throughout an organization.

Time Stamping Developer Toolkit

Some applications may benefit from the use of time stamps but lack an interface to request them.  The Time Stamping Developer Toolkit provides an easy-to-use API that enables applications to request and verify time stamps from the Thales Time Stamp Server or a server featuring Thales nShield and the Time Stamping Option Pack.
