Big Ben Time Server is Windows GPS/NTP time synchronization software from Big Ben Software Products, aimed at PCs and industrial systems that need an accurate time reference. It reads serial data from a GPS receiver, decodes the $GPRMC and $GNRMC messages in NMEA to obtain UTC time, and uses that to correct the PC BIOS or system clock. The page also highlights GNSS Anti-Spoofing Technology, and provides NPL test results, manuals, and case studies.
Functionally, this is not a general-purpose development framework, but a dedicated time synchronization tool. It supports USB/serial GPS receivers, making it suitable for scenarios that require local hardware connectivity. Platform support is mainly Windows: the main text mentions Vista/7/8/10, and also refers to XP, 7, and 10; the MSF decoder supports Windows 7, 8, 8.1, and 10. There is no information about Linux, macOS, containerized deployment, or cloud deployment.
Pricing is fairly straightforward, though the wording is somewhat confusing: the 30-day trial requires a Β£20 registration payment via PayPal, after which users email the vendor to obtain a username and password. The text also states that the software costs Β£20 for both commercial and non-commercial use. In terms of integration, it depends on a GPS or MSF receiver, USB/serial connectivity, and the K-Tron GPS ActiveX control. Case studies show it has been used as a reliable time reference for energy-site SCADA and PLC control systems.
Its strengths are the very low cost, validation through testing by the UK National Physical Laboratory, and industrial use cases such as Humbly Grove Energy. It is also relatively friendly to older Windows environments. The downsides are that the ecosystem feels rather traditional: there is no visible API/SDK, source code, or modern automated deployment guidance; registration requires PayPal plus manual email-based account issuance; and the clear hardware dependency makes it less open for secondary integration by developers.
It is best suited to companies, industrial control sites, and personal lab projects that need low-cost, localized, accurate time synchronization in a Windows environment. It is less suitable for teams that need cross-platform APIs, cloud-native integration, or large-scale automated operations. The source text does not provide information about access from China. Payment depends on PayPal, which may be a barrier for some users in mainland China. Alternatives may include commercial GPS time synchronization systems, Galleon Systems products, or standard NTP/GPS time server software.
