Regardless of the improvement - the idea is that you GET that bonus by achieving certain things within a set span of time, which can be great for filling those mid-game lulls. Opinion bump, Immigration attraction, Unity bonus, influence bonus, reduced crime, etc.

You could make it a flat bonus for all empires, or tailor them to their type and style. In simplist concepts, one could imagine that you you gain bonuses to any number of your resources. Now, how might this work in Stellaris? Lots of options really. Civ also uses a 'Heroic Age', whereby if you manage to overachieve during a Dark Age, you get a super golden age (so, falling down can potentially be a strategy to leapfrog later). Normal means nothing happens, but Golden and Dark mean your empire gains either a boost or a penalty. Once the timer ticks over, your Era score is compared to a rank system, and your empire then gains a status (Normal Age, Golden Age, or Dark Age). Now, the cool part is what happens at the end of each Era. Civ 6 also has a mechanic called 'dedications', which allows the player to pick theme (conquer, building, research, etc), and get bonus score for accomplishments in the theme. And, you get bonus points if you are say - the 1st empire in the galaxy to accomplish such a thing, you get a bonus. Most importantly, you get points toward your Era score (which resets at the end of an era, effectively).

Basically, the timeline system would be composed of a window to acknowledge and record all the little things your empire does, and give them a brief moment to shine.
