TIME(1) General Commands Manual TIME(1)
time - time a command
The given command is executed; after it is complete, time prints the
elapsed time during the command, the time spent in the system, and the
time spent in execution of the command. Times are reported in seconds.
The execution time can depend on what kind of memory the program hap-
pens to land in; the user time in MOS is often half what it is in core.
The times are printed on the diagnostic output stream.
Elapsed time is accurate to the second, while the CPU times are mea-
sured to the 60th second. Thus the sum of the CPU times can be up to a
second larger than the elapsed time.
