New submission from v kats :
Section "strftime() and strptime() Behavior" says:
"The full set of format codes supported varies across platforms, because Python
calls the platform C library’s strftime() function, and platform variations are
common. To see the full set of format codes supported on your platform, consult
the strftime(3) documentation."
It implies that this applies for strftime only, and indeed it refers to C
library’s strftime().
However, it's easy to miss (at least I got confused and lost some time), so I
propose to clarify the paragraph.
