Bug#1012035: reprotest: Salsa CI randomly fails because dpkg-source can't change timestamp

[Zhang Boyang]

Package: reprotest

Hello,

I found Salsa CI reprotest on my repo fails when "FAKETIME variation: 
faketime = [balabala]" is decided. The relevant output is:

dpkg-source: error: cannot change timestamp for 
build-experiment-1/.pc/applied-patches: Invalid argument

Full log is here:
https://salsa.debian.org/zhangboyang/bogl/-/jobs/2825734

When "FAKETIME variation: enabled but chosen randomly not to fake!" is 
decided, job finished successfully. For example:
https://salsa.debian.org/debian/bogl/-/jobs/2815352

I'm not sure if this is a problem in reprotest or somewhere else. Please 
point me out if I'm wrong.


Best Regards,
Zhang Boyang
