Struct local_clock::SystemTimeClock

pub struct SystemTimeClock { /* private fields */ }

An implementation of LocalClock backed by std::time::SystemTime.

A note on Time Travel

The time reported by std::time::SystemTime may be radically altered by external factors, such as the system operator manually setting the global system clock. If this happens, SystemTimeClock will also jump forwards/backwards in time in-tandem, depending on how far the clock was rolled back/forwards!

If this is something that concerns you, you might want to consider writing a custom LocalClock implementation backed by something akin to Linux’s CLOCK_BOOTTIME, which provides a stable monotonically increasing clock resilient against host suspends / resumes, and not subject to unexpected negative / positive time jumps.
