When parsing a std::chrono::sys_days (or a sys_time with an even longer period) we should not require a time-of-day to be present in the input, because we can't represent that in the result type anyway. Rather than trying to decide which specializations should require a time-of-date and which should not, follow the direction of Howard Hinnant's date library, which allows extracting a sys_time of any period from input that only contains a date, defaulting the time-of-day part to 00:00:00. This seems consistent with the intent of the standard, which says it's an error "If the parse fails to decode a valid date" (i.e., it doesn't care about decoding a valid time, only a date). libstdc++-v3/ChangeLog: PR libstdc++/114240 * include/bits/chrono_io.h (_Parser::operator()): Assume hours(0) for a time_point, so that a time is not required to be present. * testsuite/std/time/parse/114240.cc: New test. |
