In practice, _PyTime_t is a number of nanoseconds. Its C type is a 64-bit signed number. It's integer value is in the range [-2^63; 2^63-1]. In seconds, the range is around [-292 years; +292 years]. In term of Epoch timestamp (1970-01-01), it can store a date between 1677-09-21 and 2262-04-11. The API has a resolution of 1 nanosecond and use integer number. With a resolution on 1 nanosecond, 64-bit IEEE 754 floating point numbers loose precision after 194 days. It's not the case with this API. The drawback is overflow for values outside [-2^63; 2^63-1], but these values are unlikely for most Python modules, except of the datetime module. New functions: - _PyTime_GetMonotonicClock() - _PyTime_FromObject() - _PyTime_AsMilliseconds() - _PyTime_AsTimeval() This change uses these new functions in time.sleep() to avoid rounding issues. The new API will be extended step by step, and the old API will be removed step by step. Currently, some code is duplicated just to be able to move incrementally, instead of pushing a large change at once. |
