◆ clock_t

enum roc::core::clock_t

Clock identifier.

Enumerator

ClockMonotonic

Virtual monotonic clock.

Remarks: Starts at unspecified point of time.

When platform supports it, uses the clock source that grows monotonically. It never jumps backwards and is not affected by system clock change.

This clock is still subject to clock rate adjustments applied by NTP daemon. When it performs synchronization, it may slightly speed up or slow down both unix and monotonic clocks for a while.

Usually this clock is reset after reboot. Usually this clock does not count time spent in suspended state.

Note: If platform does not have monotonic clock source, unix clock is used. Actual precision is platform-dependent.

ClockUnix

Real-time Unix-time UTC clock.

Remarks: Starts at 1 Jan 1970 00:00:00 UTC.

May instantly jump forwards or backwards when system administrator sets time. May speed up or slow down when NTP daemon adjusts clock rate. May experience discontinuities when NTP daemon inserts leap seconds.

Note: Available on all platforms. Actual precision is platform-dependent.
