    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, time
         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.

         Time is built in to csh(1), using a different output format.

    BUGS
         Elapsed time is accurate to the second, while the CPU times
         are measured to the 100th second.	Thus the sum of the CPU
         times can be up to a second larger than the elapsed time.

         Time is a built-in command to csh(1), with a much different
         syntax.  This command is available as ``/bin/time'' to csh
         users.
