long time(0) long time(tloc) long *tloc; #include <sys/types.h> #include <sys/timeb.h> ftime(tp) struct timeb *tp;
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 defined by <sys/timeb.h>:

The structure contains the time since the epoch in seconds, up to 1000 milliseconds of more-precise interval, the local time zone (measured in minutes of time westward from Greenwich), and a flag that, if nonzero, indicates that Daylight Saving time applies locally during the appropriate part of the year.
