### 🔑 Removing Timestamps for Digital Signatures 🔑
-It's important to digitally sign Git commits and especially releases to prevent man-in-the-middle attacks. GPG signatures contain their own timestamps which can be just as bad for privacy as Git timestamps.

-Luckily, GPG signature timestamps can also be forged with the option: `--faked-system-time <iso>`. For this to be persistent, Git needs to run a version of GPG that *always* forges the system time. Also, the script should exclude GPG version information since that could also leak time information:
