uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are currently logged on, and the system load averages for the past 1, 5, and 15 minutes. so like 15 minutes prior to ur uptime command ur cpu load was 22%, 5 min prior 8%, 1 min prior 15% hope that helps and i hope im correct lol, it seems logical
