Set the initial system time to a sane (as in: not end of 21st century) value when
booting on a PC with CMOS clock set to a year before 2000. This uses 1980 (instead of 1970 as in the initial patch) as pivot year as suggested by imp in the PR followup. PR: 195703 Submitted by: cs@soi.spb.ru Reviewed by: imp MFC after: 1 weeks
