Bug#1038837: cups: transition from /etc/timezone to /etc/localtime

[bluca@debian.org]

Source: cups
Severity: normal

cups is currently referencing /etc/timezone without support for
/etc/localtime. /etc/timezone is a legacy interface that is Debian
specific. The cross-distro standard /etc/localtime (as a symlink to
the appropriate timezone file), so please switch your package to
/etc/localtime. tzsetup will stop creating /etc/timezone soon. Note
that the list of affected source packages was compiled with
codesearch, so false positives are possible. Thank you.
