template< class Duration > static std::chrono::tai_time<std::common_type_t<Duration, std::chrono::seconds>> from_utc( const std::chrono::utc_time<Duration>& ) noexcept; | (since C++20) |
Converts the utc_time
t
to a tai_time
representing the same point in time.
A std::chrono::tai_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 adding 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.).
[static] | converts tai_time to utc_time (public static member function) |
(C++20) | convert time points of one clock to another (function template) |
