# `unnecessary-source-date-epoch-assignment`

There is an assignment to a `SOURCE_DATE_EPOCH` variable in the `debian/rules` file.

As of dpkg 1.18.8, this is no longer necessary as dpkg exports this variable if it is not already set. However, you can also include `/usr/share/dpkg/pkg-info.mk` or `/usr/share/dpkg/default.mk` to ensure it is exported.

Severity: | `info`
Experimental: | `false`
