// Internal PyTime_t C API: see Doc/c-api/time.rst for the documentation.
//
// The PyTime_t type is an integer to support directly common arithmetic
// operations such as t1 + t2.
//
// Time formats:
//
// * Seconds.
// * Seconds as a floating-point number (C double).
// * Milliseconds (10^-3 seconds).
// * Microseconds (10^-6 seconds).
// * 100 nanoseconds (10^-7 seconds), used on Windows.
// * Nanoseconds (10^-9 seconds).
// * timeval structure, 1 microsecond (10^-6 seconds).
// * timespec structure, 1 nanosecond (10^-9 seconds).
//
// Note that PyTime_t is now specified as int64_t, in nanoseconds.
// (If we need to change this, we'll need new public API with new names.)
// Previously, PyTime_t was configurable (in theory); some comments and code
// might still allude to that.
//
// Integer overflows are detected and raise OverflowError. Conversion to a
// resolution larger than 1 nanosecond is rounded correctly with the requested
// rounding mode. Available rounding modes:
//
// * Round towards minus infinity (-inf). For example, used to read a clock.
// * Round towards infinity (+inf). For example, used for timeout to wait "at
//   least" N seconds.
// * Round to nearest with ties going to nearest even integer. For example, used
//   to round from a Python float.
// * Round away from zero. For example, used for timeout.
//
// Some functions clamp the result in the range [PyTime_MIN; PyTime_MAX]. The
// caller doesn't have to handle errors and so doesn't need to hold the GIL to
// handle exceptions. For example, _PyTime_Add(t1, t2) computes t1+t2 and
// clamps the result on overflow.
//
// Clocks:
//
// * System clock
// * Monotonic clock
// * Performance counter
//
// Internally, operations like (t * k / q) with integers are implemented in a
// way to reduce the risk of integer overflow. Such operation is used to convert a
// clock value expressed in ticks with a frequency to PyTime_t, like
// QueryPerformanceCounter() with QueryPerformanceFrequency() on Windows.
