template <class Duration> static std::chrono::utc_time<std::common_type_t<Duration, std::chrono::seconds>> to_utc(const std::chrono::tai_time<Duration>& t) noexcept; | (since C++20) |

Converts the `tai_time`

`t`

to a `utc_time`

representing the same point in time.

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.).

[static] | converts `utc_time` to `tai_time` (public static member function) |

(C++20) | convert time points of one clock to another (function template) |
