Perl ABCTime::HiRes - Sleep in microseconds
Time::HiRes provides a highly accurate sleep.
You can use the usleep function to sleep in microseconds. sleep function has a minimum unit of 1 second, but you can use the usleep function to sleep in milliseconds or microseconds.
use Time::HiRes 'usleep'; usleep $microseconds;
The unit is microseconds, milliseconds are a thousand times that. For example, if you want to sleep for 0.1 seconds, write:
usleep(100 * 1000);
High - precision alarm, time, interval timer
In addition to the sleep function, Time::HiRes provides precision alarms, time and interval timers.
You can set an alarm or get a sense of time of 1 second or less in units of 1 second or less.
See the Time::HiRes documentation for more information.
