PVGIS converter macro uses out of date fields

### Describe the bug

When downloading a file from https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html#TMY, the conversion to SAM CSV errors out on line 948, which deals with timestep conversions.

It looks like the converter code expects 01/01/2013 00:00:00
Whereas the actual file is:
20080101:0000

Workaround is to download an epw formatted file instead.
