This is the service type for Redshift, a program that adjusts the display color temperature according to
the time of day. Its associated value must be a
home-redshift-configuration record, as shown below.
A typical configuration, where we manually specify the latitude and longitude, might look like this:
home-redshift-configuration fields are:

Nighttime color temperature (kelvins).
Daytime screen brightness, between 0.1 and 1.0, or left unspecified.
Nighttime screen brightness, between 0.1 and 1.0, or left unspecified.
Custom time for the transition from night to day in the
"HH:MM" format. When specified, solar elevation is not
used to determine the daytime/nighttime period.
Likewise, custom time for the transition from day to night in the evening.
