Timekeeping is a fundamental component of modern computing; however, the security of system time remains an overlooked attack surface, leaving critical systems vulnerable to manipulation. This paper examines time manipulation attacks that exploit kernel vulnerabilities to distort an application's perception of time. We categorize these attacks into constant, incremental, and randomized delay strategies and analyze their impact on system performance. Through experimental evaluation, we demonstrate how adversaries can manipulate system time via dynamic library injection and syscall modification, disrupting time-sensitive applications. While Trusted Execution Environments (TEEs) offer partial isolation, they fail to address time security concerns fully. Our results highlight the challenges of securing system time and underscore the need for robust mitigation strategies.
