Although the time is expressed to the nearest hundredth of a second, the system clock is only updated 18.2 times a second (approximately every 5.5 hundredths of a second). The timestamps that you can obtain from Windows NT operating systems are limited to a maximum resolution of 10 or 15 milliseconds. | **Return Data Type:** | LONG | **Example:** **Time = CLOCK()**   **!Save the system time** **See Also:** [[standard time.htm|Standard Time]] [[setclock set system time .htm|SETCLOCK]]
