| 11 | is used to provide timing information. | |
| 12 | Output like the following | |

| 16 | tim 371:51:09 2:00.8 | |
| 17 | ovh 20:00:33 17.0 | |
| 18 | swp 13:43:20 4.6 | |
| 19 | dsk 27:14:35 4.5 | |

| 25 | The first column of numbers gives totals in the named categories | |
| 26 | since the last time the system was cold-booted; the second | |
| 27 | column gives the changes since the last time tm\b\b__ was invoked. | |
| 28 | The top left number is badly truncated and should be ignored. | |
| 29 | ovh\b\b\b___ is time spent | |
| 30 | executing in the system; | |
| 31 | swp\b\b\b___ is time waiting for swap I/O; | |
| 32 | dsk\b\b\b___ is time spent waiting for | |
| 33 | file system disk I/O; idl\b\b\b___ is idle time; usr\b\b\b___ is user execution | |
| 34 | time; der\b\b\b___ is RF disk error count (left number) and RK disk error | |
| 35 | count (right number). | |
