Guessing that you used older compiler and maybe either did not see the warnings or maybe did not generate them.

Looks like that one used SPI_MODE0 where I guessed SPI_MODE3 in the other one.

Now wondering about:

I believe all of them will be included into your sketch if you use the Arduino menu item: sketch->Include library.
We could avoid that if we updated the library.properties file and added the includes line:

I am guessing you already saw this, but there were questions asked by Arduino Developer on the Port Discovery stuff on github:

You set the callback to your function:
Then you call SD.begin() which does the FsDateTime::setCallback to it's own function.
If you really want yours, maybe make your call AFTER...
I am pretty sure that the Teensy does not retrieve the current date/time over usb or the like. Could be wrong.
I believe that the teensy has the date/time when the teensy was programmed, and maybe uses this to...
My guess is they all use some form of paint program or the like.
For my own usage I used Excel to create my own extended version of the cards, like:
Which I then print to my home printer or to PDF, like:
What I was trying to say is did you try out the currently built in stuff and it failed?
For example, here is a sketch that I hacked up:

Is the normal SD setup for setting the Create and modify date/times not working?
You created your own callback, but so does SD.
That is:

Note: if you edit boards.txt or plaform.txt, arduino likely won't see the changes as it will use its cached version.
