What does TIME+ (cpu time, hundredth) in top mean?

See the example below. Automount is showing 3019:57 in the TIME+ column.

Tasks: 241 total, 1 running, 240 sleeping, 0 stopped, 0 zombie Cpu(s): 0.7%us, 0.7%sy, 0.0%ni, 98.5%id, 0.0%wa, 0.1%hi, 0.0%si, 0.0%st Mem: 16435884k total, 15007668k used, 1428216k free, 454300k buffers Swap: 33554424k total, 140k used, 33554284k free, 1915400k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND **27026 root 15 0 974m 12m 1616 S 3.3 0.1 3019:57 automount** 4619 root 15 0 245m 24m 9444 S 2.0 0.1 3491:25 java 20515 root 15 0 15720 1532 1124 R 0.7 0.0 0:00.03 top 1 root 15 0 10372 644 548 S 0.0 0.0 0:04.87 init 2 root RT -5 0 0 0 S 0.0 0.0 2:49.80 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 1:20.90 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 3:53.73 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:34.51 ksoftirqd/1 

Does it mean it has spent an accumulated 3019 hours of CPU time?

Haven't looked at the source code of top, but it seems like 3019:57 in column TIME+ means 3019 minutes 57 seconds of accumulated CPU time.

• 999:00.00 means 999 minutes
• 1000:00 means a thousand minutes (no . separator at all)

I confirmed it on my system. I took an example process from top with 2529:38 then checked it with ps -fp PID which showed 1-18:09:38. The latter is one day and eighteen hours, which is approximately two and a half thousand minutes. Hence it equals the former.

the TIME+ column in TOP command, is not in minutes, is in hundredths of a second. source:
