Clock Drift Analysis

Clock drift analysis is the ongoing monitoring and adjustment of a computer system's internal clock to ensure it remains synchronized with a master time reference. Even with PTP, physical oscillators in servers can drift over time due to temperature fluctuations and component aging.

Financial systems must constantly measure these deviations to ensure that all recorded timestamps remain valid and compliant with regulatory standards. If drift is not corrected, it can lead to inaccurate trade sequencing and failure to meet strict reporting deadlines.

Analysis tools continuously compare local system time against highly stable atomic clocks or GNSS sources. This process is a foundational requirement for maintaining the integrity of distributed trading databases and ensuring fair execution reporting.
