std::chrono::tai_clock
Member functions
tai_clock::to_utc
Time point I/O
template< class Duration >
(since C++20)
static std::chrono::utc_time <std::common_type_t <Duration, std::chrono::seconds >>
Converts the tai_time t to a utc_time representing the same point in time.
[edit] Return value
A std::chrono::utc_time representing the same point in time as t, computed as if by constructing a value of the return type from t.time_since_epoch() and subtracting 378691210s (378691210 is the number of seconds between the epochs of the two clocks: 1958年01月01日 00:00:00 TAI and 1970年01月01日 00:00:00 UTC).
