Sure about this?  struct tm, time_t, and localtime are in K&RII, p256.
They look like part of the standard library to me.  A nonstandard
approach would be assuming that time_t is a longword containing the
number of seconds since whenever.  But using time_t as an abstract
datatype seems allowed by K&R2 (which, I know, is not the ANSI spec).
