UTCcombine
UTCcombine is a method for merging multiple time-stamped data streams that are referenced to Coordinated Universal Time (UTC) into a single consolidated time series. It is used to harmonize events recorded on different devices with clocks that may drift or skew.
The procedure involves aligning timestamps using clock offset estimation, adjusting for leap seconds, and resolving duplicate
Typical algorithms include consensus-based merging, median or weighted averaging of timestamps, and windowed deduplication. Reliability metadata
Applications include sensor networks, distributed logging, astronomy and geophysics data analysis, financial tick data consolidation, and
Implementation considerations include integration with time synchronization protocols such as NTP and PTP, handling missing or
