+
+ tm_isdst in struct tm is set to 0 to force mktime to introduce a
+ consistent offset (the non DST offset) since tm and tm+o might be
+ on opposite sides of a DST change.
+
+ Some implementations of mktime return -1 for the nonexistent
+ localtime hour at the beginning of DST. In this event, use
