time, ftime - get date and time
time_t time((time_t *)0)
struct timeb *tp;
The subroutine returns the time since 00:00:00 GMT, Jan. 1, 1970, mea‐
sured in seconds.
If tloc is nonnull, the return value is also stored in the place to
which tloc points.
The entry fills in a structure pointed to by its argument, as defined
unsigned short millitm;
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.
