Before giving up on Kicad one last attempt: ERC misery

[Efcis]

@paulvdh

Would it be a sensible test to modify the timestamps in the schematic to 8 digits with a text editor?

After truncating to 8 digits, at least I can now open the schematics (I tried with @Rene_Poschl’s cleaned-up version). But the ERC errors remain.

I’m still wondering how these 16 digits timestamps appeared.
