clock systems Shipped

What this lens looks for

The worker evaluates clock system selection and justification, understanding limitations of physical clocks, when to use Lamport timestamps, vector clocks, Hybrid Logical Clocks, or server-assigned monotonic versions based on the sync architecture (peer-to-peer vs client-server).

What its verifier checks

• Clock system chosen and justified for the architecture
• Limitations of physical clocks acknowledged (skew, leap seconds)
• HLC preferred and implemented for peer-to-peer or multi-device scenarios
• Server-assigned monotonic versions used for client-server (simpler, no clock skew)
• Clock implementation format specified (e.g., 64-bit for HLC: 32-bit counter + 32-bit clock ID)
• Clock synchronization or drift tolerance documented
