NAME¶
std::chrono::utc_clock::from_sys - std::chrono::utc_clock::from_sys
Synopsis¶
template< class Duration >
static std::chrono::utc_time<std::common_type_t<Duration, (since
C++20)
std::chrono::seconds>>
from_sys( const std::chrono::sys_time<Duration>& t );
Converts a sys_time t to a utc_time u that represents the same point in
time.
u.time_since_epoch() - t.time_since_epoch() is equal to the number of leap
seconds
that was inserted between t and 1 January 1970. If t is the exact date of a
leap
second insertion, that leap second is counted as inserted.
Return value¶
A utc_time representing the same point in time as t.
