timing

The contents of this module can be included with the header hpx/modules/timing.hpp. These headers may be used by user-code but are not guaranteed stable (neither header location nor contents). You are using these at your own risk. If you wish to use non-public functionality from a module we strongly suggest only including the module header hpx/modules/timing.hpp, not the particular header in which the functionality you would like to use is defined. See Public API for a list of names that are part of the public HPX API.
