R: Return the current high-resolution real time.

hires_time {bench} | R Documentation

## Return the current high-resolution real time.

### Description

Time is expressed as seconds since some arbitrary time in the past; it is not correlated in any way to the time of day, and thus is not subject to resetting or drifting. The hi-res timer is ideally suited to performance measurement tasks, where cheap, accurate interval timing is required.

### Usage

    hires_time()

### Examples

    hires_time()

    # R rounds doubles to 7 digits by default, see greater precision by setting
    # the digits argument when printing
    print(hires_time(), digits = 20)

    # Generally used by recording two times and then subtracting them
    start <- hires_time()
    end <- hires_time()
    elapsed <- end - start
    elapsed
