function tic() {
	var parts;
	var t;

	// Get a millisecond timestamp and convert to seconds:
	t = ts() / 1000;

	// Decompose the timestamp into integer (seconds) and fractional parts:
	parts = modf( t );

	// Convert the fractional part to nanoseconds:
	parts[ 1 ] = round( parts[1] * 1.0e9 );

	// Return the high-resolution time:
	return parts;
}
Returns a high-resolution time.

## Notes

-   Output format: `[seconds, nanoseconds]`.

@private
@returns {NumberArray} high-resolution time

@example
var t = tic();
// returns [<number>,<number>]
