             Bug #: 11321
           Summary: Warn on folded constants that look like bad date math
           Product: clang
           Version: 2.8
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Static Analyzer
        AssignedTo: [email protected]
        ReportedBy: [email protected]
                CC: [email protected]
    Classification: Unclassified


In celebration of the DST transition today, please consider adding a static
analyzer check for the folded constant 86400 (24*60*60), either integer or
floating point. Days do not necessarily have 86400 seconds and any occurrence
of this constant almost certainly represents such an assumption.
