Thanks for the information, I wasn't aware this (the man page mentions
problems with faketime, but not in the combination with quilt patched

No idea, I'm only a user of Salsa CI, but I'll open an issue there to
ask them to undo the change they introduced around the beginning of
March until the root cause of this is fixed.
