systime_ns

datetime

Returns the current system time in nanoseconds

Syntax

systime_ns()

number

System time in nanoseconds since epoch

Get high-precision timestamp

Input:

systime_ns()

Output:

1735124445123456789

Add high-precision timestamps

Input:

map({precise_ts: systime_ns()})

Output:

Add nanosecond timestamp to records

Compute precise durations

Input:

(systime_ns() - .start_ns) / 1000000000

Output:

Calculate elapsed seconds from nanoseconds

The systime_ns() function returns the current system time in nanoseconds since the Unix epoch, providing high-precision timing.

Use systime_ns() for high-precision timing measurements, performance benchmarking, or when you need sub-second timestamp accuracy.
