clarify documentation/configuration/sample to configure times better?

Is your feature request related to a problem? Please describe. User preferences should be able to completely override/replace location (and all natural time intervals as if nonexistent). One philosopher said a 'solar civilization' calendar would be based on overall solar time (though don't recall this in detail) so presumably average arise 4AM, sleep 8PM (even if not always real dawn & dusk)... but typical POSIX-based OS colour shifting programs for nighttime use location and few/no separate settings.

Describe the solution you'd like Please just let users set their own schedules (at least to full extent of KDE/Plasma night colour control program you link, which also lets you set duration from instant to several/many (though unfortunately limited) hours to complete colour shift). Thanks for allowing users set dawn & dusk, but I set 5:00-11:00, 20:15-12:30 (fake/daylight_saving but system time) and it said invalid (with no explanation nor documentation of 'valid' and why forced) but I want to use anyway (summary above; detail below).          Maximum screen brightness & dullness & standard gamma should be mentioned, all which I think are different than redshift.conf (I think X/KDE starts at 6500, gamma 1, which I forgot what means but maybe should shift or I keep standard).

Describe alternatives you've considered Xflux (used to use, too old), X/KDE Plasma night colour control (but KDE is slow/halts for large worklaods XFCE is very fast at).

Additional context Where I live dawn can be in 10AM hour and dusk in 3PM hour, which simply can't be forced while even be considered anything close to usable, let alone a friend who says lives in igloo (months/seasons to each night/day colour shift).         I'm a computer scientist/programmer, some whom have different schedules (night shift, etc.) so though I want my night colour shift to encourage sleep at 8PM (on schedule described) for alternative/now it'd be nice if can use dusk interval above until can gradually decrease to daytime schedule (until next time I do all-night projects)... however redshift.conf says transition is seconds but that's too much at once if I have things to work on at night and even if I get up early but don't want full screen brightness until later. My curtains block almost all light so if happens I'm up early-to-mid morning chances are I almost never want screen brightening yet (except interval above) unless can return to daytime schedule and decrease interval to something such as 3:45AM to 7AM.          Even if a night colour control program finishes dusk red shift at midnight, sometimes I instead use main monitor's blue light filter and briefly turn off night colour control software so can see/finish a few things... so may help to temporarily extend dusk red shift interval to 3AM or 4AM.

Apparently the control is there but redshift.conf.sample has bad example: it needs to use 24-hour time. Clearly whoever wrote that sample doesn't actually use it...
