Fixes #902.
ZIP stores modification times as timezone-naive local clock values. Ouch previously treated those values as UTC during extraction and wrote UTC clock values when creating archives, shifting file times by the local UTC offset.
Archive creation now converts filesystem timestamps to the applicable local offset before writing the ZIP timestamp. Extraction resolves the local offset for the stored date and converts that clock value back to the corresponding filesystem timestamp, including historical daylight-saving offsets.
Tests cover a fixed non-UTC offset and the host's actual local offset.
