from_utc( const std::chrono::utc_time<Duration>& ) noexcept;
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.)
to_utc converts tai_time to utc_time
