A collection of ways to fetch the current time.
primitive val Time
new val create() : Time val^
The wall-clock adjusted system time with nanoseconds. Return: (seconds, nanoseconds)
fun box now() : (I64 val , I64 val)
The wall-clock adjusted system time.
fun box seconds() : I64 val
Monotonic unadjusted milliseconds.
fun box millis() : U64 val
Monotonic unadjusted microseconds.
fun box micros() : U64 val
Monotonic unadjusted nanoseconds.
fun box nanos() : U64 val
Processor cycle count. Don't use this for performance timing, as it does not control for out-of-order execution.
fun box cycles() : U64 val
Get a cycle count for beginning a performance testing block. This will will prevent instructions from before this call leaking into the block and instructions after this call being executed earlier.
fun box perf_begin() : U64 val
Get a cycle count for ending a performance testing block. This will will prevent instructions from after this call leaking into the block and instructions before this call being executed later.
fun box perf_end() : U64 val
fun box eq( that: Time val) : Bool val
fun box ne( that: Time val) : Bool val
Return a clock time on linux and bsd.
fun box _clock_gettime( clock: (_ClockRealtime val | _ClockMonotonic val)) : (I64 val , I64 val)
Return QPC and QPF.
fun box _query_performance_counter() : (U64 val , U64 val)
