[libcamera-devel] [PATCH v3] libcamera: Add build time to version string for dirty builds

[Niklas Söderlund]

Having the build time in the version string is useful when building from
a dirty worktree and deploying to targets as a quick way to identify the
binary has been deployed successfully.

Before this change the version string is reported as

    libcamera v0.0.0+1692-aaff196a-dirty

While with this change the version string is reported as

    libcamera v0.0.0+1692-aaff196a-dirty (2020-08-05T22:42:18+02:00)
