% uname -a
SunOS zeus 5.7 Generic sun4m sparc SUNW,SPARCstation-20
% grep typedef.\*\\\<time_t /usr/include/sys/*
/usr/include/sys/siginfo.h:typedef      long    time_t;         /* time of day in seconds */
/usr/include/sys/stat.h:typedef long    time_t;         /* time of day in seconds */
/usr/include/sys/time.h:typedef long    time_t;         /* time of day in seconds */
/usr/include/sys/types.h:typedef        long            time_t; /* time of day in seconds */
