Clock

cajeta.time.Clock — the static “what time is it” surface, modeled on the clock-access parts of java.time.Clock / System. nanoTime() is a monotonic counter (CLOCK_MONOTONIC) for measuring elapsed intervals — it is not wall-clock time and is unaffected by NTP adjustments. millisTime() is wall-clock milliseconds since the Unix epoch (CLOCK_REALTIME) and can jump if the system clock is adjusted. now() reads the wall clock as an Instant. All members are static; there is nothing to construct.

int64 start = Clock.nanoTime();
Instant moment = Clock.now();
int64 elapsedNanos = Clock.nanoTime() - start;

Methods

Signature
static int64 nanoTime() ⚑Monotonic nanosecond counter for interval measurement (CLOCK_MONOTONIC)
static int64 millisTime()Wall-clock milliseconds since the Unix epoch (CLOCK_REALTIME)
static Instant now() ⚑The current instant from the system wall clock (millisecond resolution)
