What is FSMLabs and what does its TimeKeeper software do?

Updated

FSMLabs is an enterprise clock-sync software company. Its product line, TimeKeeper, synchronizes the clocks of servers, virtual machines, and applications to multiple time sources over the network, and is positioned for organizations that need accurate, reliable, and verifiable time rather than default OS time handling. The site presents it as used by large banks, major stock exchanges, and other Fortune 500 customers, with financial services as a prominent use case.

What problem TimeKeeper addresses

Most servers rely on a default time service that can drift, depend on a single source, or fail silently. TimeKeeper instead treats time as an infrastructure layer: it takes multiple time sources, distributes time across the network, and lets operators see and verify the result. The site frames the value in three words — accurate, reliable, and verifiable — and ties reliability features such as failover and event notification to reduced operational risk.

The three product layers

Layer What it is What it does
Platform Integrated dashboard Manages all TimeKeeper products in one place
Server Grandmaster / boundary clock Uses network timing and GNSS time server appliances as multiple time sources; serves and receives time over NTP/PTP and other protocols
Client Active Client software Synchronizes clocks on Linux, Windows, and Solaris application servers and VMs to multiple sources over the network, targeting sub-microsecond sync

The chain works top-down: the Server layer anchors time from external sources, the Client layer pulls that time onto individual machines, and the Platform layer gives a single view across the deployment.

Where it fits

The site organizes solutions by industry and environment: financial services, 5G, IoT, automation, broadcast, cloud, database, cybersecurity, data center, and gaming. The common thread is workloads where timestamp order or interval accuracy matters — for example, sequencing transactions and logs across machines in a bank or exchange, or keeping distributed systems consistent when clocks disagree.

What to check before deciding

  • Protocol fit. Confirm your environment's mix of NTP and PTP, since the Server layer is described as serving and receiving time over both plus other protocols.
  • OS coverage. The Client layer is documented for Linux, Windows, and Solaris; verify your specific versions.
  • Source redundancy. The multi-source design is the core reliability argument, so map which GNSS and network sources you can actually provide.
  • Verification needs. If auditability of time is a requirement, the "verifiable" claim and the Platform dashboard are the parts to evaluate in a demo.

The site offers a "Book a Demo" entry point and published customer quotes from KOR Group LLC, KCG, and Sanjay Navgale; pricing and licensing terms are not stated on the page, so those need to come from FSMLabs directly.
