zclock_sleep (int msecs);
// Return current system clock as milliseconds. Note that this clock can
// jump backwards (if the system clock is changed) so is unsafe to use for
// timers and time offsets. Use zclock_mono for that instead.

zclock_time (void);
// Return current monotonic clock in milliseconds. Use this when you compute
// time offsets. The monotonic clock is not affected by system changes and
// so will never be reset backwards, unlike a system clock.
CZMQ_EXPORT int64_t
zclock_mono (void);
// Return current monotonic clock in microseconds. Use this when you compute
// time offsets. The monotonic clock is not affected by system changes and
// so will never be reset backwards, unlike a system clock.
