[section Time Action]

This example shows how to use the `testing.time` utility to show time
information for building a target.

Files:

* [@../../example/time/jamroot.jam jamroot.jam]
* [@../../example/time/hello.cpp hello.cpp]

Our `jamroot.jam` specifies the target we build and the `time`
declaration to time the target we build:

[import jamroot.jam]

[jamroot]

Building the example yields:

[teletype]
```
> cd /example/time
> b2
...found 9 targets...
...updating 6 targets...
common.mkdir bin
common.mkdir bin/clang-darwin-4.2.1
common.mkdir bin/clang-darwin-4.2.1/debug
clang-darwin.compile.c++ bin/clang-darwin-4.2.1/debug/hello.o
clang-darwin.link bin/clang-darwin-4.2.1/debug/hello
testing.time bin/clang-darwin-4.2.1/debug/hello.time
user: [hello] 0.013509
system: [hello] 0.045641
clock: [hello] 0.000000
...updated 6 targets...
```

[note The actual paths in the `bin` sub-directory will depend on your
toolset.]
