Neither
.arg timer
nor
.arg result
shall be a null pointer.
If there is a runtime-constraint violation, there is no attempt to convert the time.
.rtconst end

.desc begin
The &func function converts the calendar time pointed to by
.arg timer
into a broken-down time, expressed as UTC. The broken-down time is stored in
the structure pointed to by
.arg result.
.desc end

.return begin
The &func function returns
.arg result,
or a null pointer if the specified time cannot
be converted to UTC or there is a runtime-constraint violation.
