| 7 | .SH DESCRIPTION |
| 8 | The |
| 9 | given command is executed; after it is complete, |
| 10 | .I time |
| 11 | prints the elapsed time during the command, the time |
| 12 | spent in the system, and the time spent in execution |
| 13 | of the command. |
| 14 | Times are reported in seconds. |
| 15 | .PP |
| 16 | The execution time can depend on what kind of memory |
| 17 | the program happens to land in; |
| 18 | the user time in MOS is often half what it is in core. |
| 19 | .PP |
| 20 | The times are printed on the diagnostic output stream. |
| 21 | .SH BUGS |
| 22 | Elapsed time is accurate to the second, |
| 23 | while the CPU times are measured |
| 24 | to the 60th second. |
| 25 | Thus the sum of the CPU times can be up to a second larger |
| 26 | than the elapsed time. |
