Executes command (which must be a simple command, not an alias, a pipeline, a command list or a parenthesized command list) and prints a time summary as described under the time variable.

If necessary, an extra shell is created to print the time statistic when the command completes.

Without command, prints a time summary for the current shell and its children.

This is a tcsh shell command /usr/bin/time .
The csh has its own and syntactically different builtin version of time
