FTPL (FakeTime Preload Library, aka libfaketime) intercepts various system library calls and tricks programs of your choice into seeing a faked system time without having to change the time system-wide. This can be used for running legacy software with Y2K bugs, testing software for year-2038 compliance, debugging time-related issues such as expired SSL certificates, and using software that ceases to run outside a certain time frame. The faked time can be specified either absolutely or relative to the real current time, and optionally also affects file timestamps. The faked clock continues to run, but can optionally be frozen, slowed down, or made faster. A wrapper script "faketime" simplifies the usage, similar to tools such as fakechroot.
RELEASE NOTES: New features: support for nanosecond resolution, saving timestamps to files, speeding up/slowing down per-process timers, and faking system calls such as sleep() and alarm(). Adds an option to use the same global clock setting for all libfaketime-spawned processes. Support for advancing the time with each time-related system call ("deterministic time"). A new "timeprivacy" wrapper ensures that programs are started with unique timestamps. Fixes: significantly improved support for OSX; fixed support for recent glibc versions; and improved compatibility with multiarch/multilib Linux systems.
