NAME

time − time a command

SYNTAX

time command

DESCRIPTION

The time command times the execution of the specified command.  That is, time displays the elapsed time during the command, the time spent in the system, and the time spent in execution of the command.  All times are reported in seconds. 

The execution time can depend on what kind of memory the program happens 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. 

RESTRICTIONS

Elapsed time is accurate to the second, while the CPU times are measured to the 60th second.  Thus the sum of the CPU times can be up to a second larger than the elapsed time.
