While preparing to run Hammers of the God this Saturday, I lined up the timeline presented in the dungeon's library books with the timeline from the GURPS Myth book (as well as my own small alterations). I figured I would go ahead and post it here as an example of how this kind of thing might look.
All instances of "goblins" in the library books should be replaced with references to Ghols. Similarly, "Giants" should be replaced with Trow, "Elves" should be replaced with Forest Giants, and "Halflings" should be replaced with Fir'Bolg.
I'm listing the stuff from Hammers of the God simply as "Book 1" and so on, because I don't want to spoil the secret Dwarven history presented in the adventure for anyone who hasn't read or played it yet.
No one remembers what "HC" stands for, but it's basically the Myth equivalent of "BC" or "BCE." As for "AE," it stands for "Acit El," which means "Golden Age" in the ancient Bruig language. It refers to the year Clovis founded the Cath Bruig Empire.
The Ages are 1,000-year periods that are considered either "Light" or "Dark," depending on who was in charge of the know world and/or how bad things were for humans in general. The general consensus is that the world changes from Light to Dark and back again every millennium, but recorded history is not long enough to confirm this. The Trow could shed more light on this issue, but they are not very talkative (outside of some rare occasions when they won't shut up), and they might not be reliable narrators anyway.
If my math is wrong, I apologize. The fact that there is no Year 0 kept throwing me off by a year, and I've lost track of how well I've fixed the problem.
One more note: there has been debate online among Myth fans about whether or not the GURPS Myth timeline is accurate. I usually consider things from the computer games more canonical than stuff from the GURPS book, but in this case it was just easier to defer to the book. Please don't take my timeline as definitive outside of this particular RPG campaign. Of course, if you want to create a Myth tabletop campaign of your own, feel free to borrow this timeline if you wish; I just don't want to claim this is accurate to the original source material.

1 AE Clovis founds the Cath Bruig Empire. Llancarfan is renamed Muirthemne.
180 AE The Trow enslave the Oghres and several other species. Some claim this was also around the time the Trow invented ironworking, while other accounts insist they possessed iron tools since the Axe Age. One possibility is that the Trow refined their metalworking techniques this year, boosting their technological capabilities in the realms of construction and military endeavors.

2311 to 2331 AE The Twenty Years' War takes place in the Province, which becomes semi-independent from the Empire.
2422 AE Balor summons the Fetch to the world of Myth.
2431 AE Balor and the Fallen Lords begin their invasion. They burn Muirthemne and the surrounding lands with magical fire, creating the Barrier. Some accounts claim this is when the Heron Guards became the Journeymen.
Sword Age - 2431 AE to Present - "Should" be a Dark Age, but many believe the cycle to be broken.
2458 AE Pirates of Leix loot Tyr. The Avatara Maeldun takes revenge on the pirates.
2463 AE The government of the Province, the Dwarves (fleeing their Ghol-infested cities), the Journeymen and "Berserks" from east of the Cloudspine, and the Forest Giants officially join forces, and the Great War begins in earnest. Some accounts claim that the Fir'Bolg joined the Light coalition at this time, as well.
2465 and 2466 AE The Light forces hold back the Dark at Bagrada.
2467 AE The Light forces repel the Dark at Seven Gates.
2468 AE The Forest Giants fail to appear. The Dark forces make it through the under-defended Cloudspine and raze Covenant.
2471 AE The Dark forces sack Tyr.
2473 AE The Nine, composed of the remaining Avatara, take command of the forces of Light.
2476 AE Some sources claim this is the year the Fir'Bolg joined the forces of Light.

2481 AE Strangely, the comet heralding the coming of the Leveller does not appear until this year, instead of the expected year of 2431 AE.

2562 AE By this year, most of the World Knots have been repaired and "reprogrammed" to only function with the use of Key Pendants. These pendants and the use of the World Knots are carefully controlled by the imperial government.
2692 AE Under mysterious circumstances, Emperor Alric abdicates the throne and disappears. His successor, Emperor Myrdred, takes the throne. Conspiracy theories abound for some time that this is the same Myrdred once known as The Deceiver, a Fallen Lord, but all credible accounts claim that The Deceiver died explosively in battle. Most doubts are put to rest when Emperor Myrdred proves to be a just and capable ruler.
2822 AE Regulations on the use of World Knots are greatly relaxed, although the ownership of Key Pendants is still tracked carefully.
2841 AE The Lamentations of the Fallen Lords campaign begins.
3431 AE Assuming the Cycle is not broken, this is a possible future return date of the Leveller.
3481 AE Assuming the Cycle is not broken, this is another possible future return date of the Leveller.
