Synopsis

    time command
    time [command]

Execute command and print the total elapsed time, user time, and system time (in seconds). Same as the Unix command time (see Chapter 2), except that the built-in version can also time other built-in commands as well as all commands in a pipeline.

The second form applies to ksh93; with no command, the total user and system times for the shell, and all children are printed.
