std::chrono::utc_clock
Member functions
utc_clock::to_sys
Time point I/O
Leap second insertion information
template< class Duration >
(since C++20)
static std::chrono::sys_time <std::common_type_t <Duration, std::chrono::seconds >>
Converts a utc_time t to a sys_time representing the same point in time (if possible).
If t represents a time point during a leap second insertion, the last representable value of sys_time prior to the insertion of the leap second is returned. In all other cases, utc_clock::from_sys(utc_clock::to_sys(t)) == t.
[edit] Return value
A sys_time representing the same point in time as t, or the last representable value prior to the insertion of the leap second if t represents a time point during a leap second insertion.
