Make TestStand support both local and UTC formats.

[StephenGerads]

1) TestStand functions Time() and Date() only output local format; they should support both local and UTC format. (Like LabVIEW's Format Date/Time String)

 
2) TestStand configuration options should have a setting(s) for:
report time format local / UTC
datalogging time format local / UTC

Good Idea; this is just what I need actually.
