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>:

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 appro‐
priate part of the year.
