This is one of many commendations introduced with the Timewalking events. They grant reputation with various factions from previous expansions.

Here are some further notes on these commendations:

The commendations are Bind on Account, and can be sent to other characters. Hence, you can earn 时空扭曲徽章s to buy these on an alt, to send to your main.
Each commendation grants 500 reputation at baseline. The amount granted can be increased by any reputation buffs, such as the following (note that some of the following buffs stack):

耶！, available by riding the carousel during the Darkmoon Faire
恐怖面容/无忧者, available during the Hallow's End Holiday Event
分享之魂, available during the Pilgrim's Bounty Holiday Event
外交, one of the human racial abilities

Below are listed the commendations available from each event. Note that each vendor (and the items that vendor sells) are exclusive to a specific Timewalking event. For example, 凯普丽 is only available during Burning Crusade Timewalking, and not during Catclysm Timewalking.
For the sake of completionists, "Items of Note" are listed for each faction, including the recipes/patterns for various trades, mounts, and notable Transmog weapons/shields. These are NOT comprehensive lists of items - some other low level gear potentially useful for transmog has been left out.

EARNING 时空扭曲徽章s

Quests
Maximum earnable: 500 时空扭曲徽章s per timewalking week

There is a weekly quest associated with each Timewalking event. This quest is started by an item dropped by the last boss in the first Timewalking dungeon you complete during the event, and rewards 500 badges.
Some further notes:

Once one of these items has been looted by a character, they WILL NOT drop again for the remainder of the week for that character (even if you don't turn in the quest right away) - if you delete it you won't get another!
This quest can be completed once per Timewalking event PER CHARACTER. This means you can do this on alts to get an easy 500 badges (plus however many for the single dungeon) and save up for items you are wanting.

You cannot transfer the badges, but your alts will have to spend what they have earned. That being said, toys, mounts and heirlooms are account bound, and the commendation reputation tokens (e.g. 沙塔尔奖章) as well as some other vanity items (e.g. 灰齿的獠牙) are BoA and can be mailed to other characters.
Dungeons can be run until the end of the event on Monday night. The event vendors (who are also the quest turn-in NPCs) remain accessible for an additional 24 hours, and they disappear on Tuesday nights following the event.
Dungeons
Maximum earnable: Unlimited 时空扭曲徽章s per timewalking week (30-40 per dungeon)

Dungeons are repeatable over and over to earn Timewalking badges. These can be completed from the start of the event on a Wednesday through to the completion of the event on Monday.
Note that the following level requirements exist to do a Timewalking dungeon:

Burning Crusade Timewalking: Level 71+
Wrath of the Lich King Timewalking: Level 81+
Cataclysm Timewalking: Level 86+

SPENDING 时空扭曲徽章s

During different Timewalking events (Burning Crusade, Wrath of the Lich King, and Cataclysm) specific Timewalking vendors are available with unique items. This means that certain items are available from only one vendor, and the vendors from other Timewalking events will not carry them!

An important thing to note is that each vendor is available ONLY during the corresponding event. For example, 凯普丽 is only available during the week of the Burning Crusade Timewalking event, and will not be available during the Wrath of the Lich King and Cataclysm Timewalking events. Each vendor will be available from the beginning of the event until 24 hours AFTER it is finished (in case you like to make last minute purchases).

The items available for 时空扭曲徽章s include mounts, toys, and various vanity/utility items, as well as Timewarped gear. The gear is unique, in that it will scale to the level of the character that buys it.
It should be noted that the scaling is ONLY when the item is purchased - as such, the item is stuck at the level at which it was purchased (e.g. If you purchase 占星者的聚焦匕首 at level 76, the item will retain stats scaled to level 76, even if that character levels to 77 or higher).

While the individual gear list is too extensive to include below, each slot has a set price, as in the chart below.
Gear from certain slots are available from specific vendors but not from others (e.g. helms are only available from 凯普丽 during Burning Crusade Timewalking, and they are not available during Wrath of the Lich King Timewalking). The exception to this are trinkets, which are available during multiple events.
