TIME(2) System Calls Manual TIME(2) NAME time, ftime - get date and time SYNOPSIS long time(0) long time(tloc) long *tloc; #include <sys/types.h> #include <sys/timeb.h> ftime(tp) struct timeb *tp; DESCRIPTION Time returns the time since 00:00:00 GMT, Jan. 1, 1970, measured in seconds. If tloc is nonnull, the return value is also stored in the place to which tloc points. The ftime entry fills in a structure pointed to by its argument, as de- fined by <sys/timeb.h>: /*- * SPDX-License-Identifier: BSD-3-Clause * * Copyright (c) 1991, 1993 * The Regents of the University of California.
