The Bureau of Temporal Regulation
As the Bureau of Temporal Regulation is an interdimensional organization tasked with keeping the timeline straight (a very thankless job), the BTR is familiar with a great many cultures that have developed time travel. If your pups are from such a culture and a regular time traveler, or at least deals with time travel on a regular basis, feel free to have encountered the BTR at some point or have knowledge of them, including having contact with a liaison between your pup's government and the BTR.
Weyland himself is not personally familiar with a great many worlds, however he at least has access to knowledge of various time traveling civilizations through a database he carries. He also would have the phone numbers, or equivalent, to any liaison between the BTR and a time traveling society.
The BTR preaches non-interference and frown upon any one making changes to the timeline. They will also levy fines upon anyone that violates the timeline. (List of Temporal Violations)
The head of the BTR is Minister Harriet Andertown-Stovely
If your pup has had some fun with time travel or is from a time traveling society, please let me know how you would like Weyland to handle it, be it knowing about them or not!
This doesn't mean that Weyland has actually met them but whether or not the BTR would have contacts with their society or have interacted with your character at some point. Like having been fined by some other BTR agent which would be listed in Weyland's computer Database.
Feel free to handwave previous interactions with a humorless bureaucrat with a penchant for paperwork and absolute disgust at the idea of going back in time to make make the world a better place or time travel for fun or things of that nature.
