A detail I think you might be missing is that _NETBSD_SOURCE is
defined by default, in <sys/featuretest.h>, which <time.h> pulls in
(the comments in that file may be helpful to understanding the
situation). So a program compiled with no special definitions or flags
*does* see the definition of strptime(), which agrees with the man
page. The circumstance in which _NETBSD_SOURCE isn't defined is when
some other feature-environment symbol, like _POSIX_C_SOURCE, is
defined.

Probably (a) not defining whatever feature macro it's currently
defining, out of a misguided sense of cleanliness, or (b) selectively
adding _XOPEN_SOURCE to the set of feature macros it defines, to get a
XOPEN function.
