Bug Fix on TMY export for dataframe size

[vicford]

Description of PR

Summary of changes and related issue The size of TMY dataframes prepared for export did not conform to the explicit standard of 8760 size. This was largely because of converting to local time producing a mismatch in hours. Several cases were then produced:

• An extra hour was included (size 8761)
• A missing hour (size 8759)
• Leap days were included if a model that has leap days had a Feb with a leap year selected (size 8784)
• Leap days and a missing hour (size 8783)
