This seems like a dumb question, but I've done a good bit of research and still haven't come up with an answer. All I'm trying to do is get my teensy 4.1's clock to sync to my laptop's time at first boot, but I haven't found a clear answer for how to do it yet. Can someone point me in the right direction?

How to set RTC on Teensy 4.1?

@nAnd:
From the Arduino IDE, open, build, & run the example sketch titled "TimeTeensy3", which shows how to accomplish syncing the RTC inside the T4.1 (assuming you have a battery properly wired up to it) with local time in the T4.1. And, to go along with that, local time in the T4.1 is set from the PC each & every time that you upload a new program to the T4.1.
You can then include the pertinent parts in your own sketches to apply the same syncing when your sketch is loaded/running.
Hopefully that answers the question that you were asking . . .
