I expect so, yes.

Yes, that's pretty much the same code in strftime,
regardless of platform.

There is another issue here: Emacs currently supports
time stamp resolution only to the nearest microsecond.
Gnulib supports nanosecond resolution, which will go
unused inside Emacs's format-time-string function at first.

At some point Emacs can be improved to support
nanosecond-resolution time stamps, but that is
a different task.
