Time zone information from date stamps is lost

[unguiculus]

GCViewer parse date stamps correctly but turns them into Date objects. Unfortunatley, this is due to restrictions in the Date API. A Date does not handle time zones and a date string can only be parsed into a Date using SimpleDateFormatter.

As a solution, GCViewer should update to Java 8 and use the new Date and Time API which allows to parse a date stamp into a ZonedDateTime object.
