## Description

    kres rtclock

## Performance

Read the real-time clock from operating system. Under Windows, this changes only once per second. Under GNU/Linux, it ticks every microsecond. Performance under other systems varies.

## Examples

Here is an example of the rtclock opcode. It uses the files rtclock.orc and rtclock.sco.

Example 333. Example of the rtclock opcode.

    /* rtclock.orc */
    ; Initialize the global variables.
    sr = 44100
    kr = 44100
    ksmps = 1
    nchnls = 1

    ; Instrument #1
    instr 1
      ; Get the system time.
      k1 rtclock
      ; Print it once per second.
      printk 1, k1
    endin
    /* rtclock.orc */

    /* rtclock.sco */
    ; Play Instrument #1 for two seconds.
    i 1 0 2
    e
    /* rtclock.sco */

Its output should include lines like this:

     i   1 time     0.00002: 1018236096.00000
     i   1 time     1.00002: 1018236224.00000
