TIME(1) UNIX Programmer's Manual TIME(1)

NAME

    time - time a command

SYNOPSIS

    time command

DESCRIPTION

    The given command is executed; after it is complete, _t_i_m_e
    prints the elapsed time during the command, the time spent
    in the system, and the time spent in execution of the com-
    mand.  Times are reported in seconds.

    On a PDP-11, 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.

BUGS

    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.
