std::chrono::gps_clock::to_utc
| template <class Duration>
static std::chrono::utc_time<std::common_type_t<Duration, std::chrono::seconds>>
    to_utc(const std::chrono::gps_time<Duration>& t) noexcept; | (since C++20) | 
Converts the gps_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 adding 315964809s. (315964809 is the number of seconds between the epochs of the two clocks: 1980-01-06 00:00:00 UTC for gps_clock and 1970-01-01 00:00:00 UTC for utc_clock.).
