Windows FILETIMEs before 1970 are projected into the future

Reported by: Marc Halbruegge <marc.halbruegge@…> Owned by: az_sw_dude
Milestone: Boost 1.38.0 Component: date_time
Version: Boost 1.37.0 Severity: Problem
Keywords: ms windows filetime Cc:

Description

When the file time is before 1970 (possible e.g. in ntfs file systems), the conversion produces an integer overflow, projecting the file time some 60,000 years into the future.

Unfortunately, this causes bad_date exceptions to be thrown later on
