std::chrono::tai_clock::to_utc - std::chrono::tai_clock::to_utc


template< class Duration >

static std::chrono::utc_time<std::common_type_t<Duration, (since C++20)

to_utc( const std::chrono::tai_time<Duration>& t ) noexcept;

Converts the tai_time t to a utc_time representing the same point in time.

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:
1958-01-01 00:00:00 TAI and 1970-01-01 00:00:00 UTC).
