No.

datan:>grep time_t /usr/include/sys/types.h 
typedef long            time_t; /* time of day in seconds */
datan:>uname -a
SunOS datan 5.7 Generic sun4u sparc

But...

datan:>cc -o foo32 foo.c 
datan:>./foo32
sizeof(time_t) = 4
datan:>cc -xarch=v9 -o foo64 foo.c 
datan:>./foo64
sizeof(time_t) = 8
