Kernel Hardware Timestamps - Quant Developer Interview Question

Problem Description

Precise latency tracking in high-frequency trading requires capturing hardware timestamps stamped directly by the Network Interface Card (NIC). This process involves parsing binary kernel control messages to extract specific timestamp structures, enabling accurate wire-to-application performance analysis. Task Implement a parser that extracts the raw hardware timestamp from a binary control message buffer. The function must iterate through cmsghdr structures, handle 64-bit memory alignment, and
