C++ representation of time duration, time point, and clocksThis package forms part of the Boost C++ Libraries collection.
.
The Boost.Chrono library provides:
.
* A means to represent time durations: managed by the generic duration
class.Examples of time durations include days, minutes, seconds and
nanoseconds, which can be represented with a fixed number of clock
ticks per unit. All of these units of time duration are united with
a generic interface by the duration facility.
* A type for representing points in time: time_point. A time_point
represents an epoch plus or minus a duration. The library leaves
epochs unspecified. A time_point is associated with a clock.
* Several clocks, some of which may not be available on a particular
platform: system_clock, steady_clock and high_resolution_clock. A
clock is a pairing of a time_point and duration, and a function
which returns a time_point representing now.
.
To make the timing facilities more generally useful, Boost.Chrono
provides a number of clocks that are thin wrappers around the
operating system's time APIs, thereby allowing the extraction of wall
clock time, user CPU time, system CPU time spent by the process:
.
* process_real_cpu_clock, captures wall clock CPU time spent by the
current process.
* process_user_cpu_clock, captures user-CPU time spent by the current
process.
* process_system_cpu_clock, captures system-CPU time spent by the
current process.
* a tuple-like class process_cpu_clock, that captures real, user-CPU,
and system-CPU process times together.
* a thread_clock thread steady clock giving the time spent by the
current thread (when supported by a platform).
.
Lastly, Boost.Chrono includes typeof registration for duration and
time_point to permit using emulated auto with C++03 compilers.
