MarsSeed [1] filed a deletion request for redshift-scheduler [2]: Unneeded addon to Redshift, discontinued since 2019.
Current Redshift has the same feature, as noted by a user in 2021 in a GitHub issue created for redshift-scheduler. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/redshift-scheduler/
