second

Interface

Second

Returns the hour within a serial Julian date and time values. Care must be taken in handling rounding errors appropriately, because time is expressed as a fraction of a 24hr day. Therefore 1sec is ~0.000015 days. Given this fraction, this function first calculates the number of seconds that have lapsed into the current day, rounding to the nearest second. The seconds that make up a whole number of minutes are then subtracted with the remainder being the number of seconds in the current minute.

Example 1

#include <stdio.h>
#include <codecogs/units/time/now.h>
#include <codecogs/units/time/second.h> 
using namespace Units::Time;
 
int main()
{
  printf("\n The current second using USA daylight saving is", second(now(st_USA)));
  printf("\n The current second using European daylight saving is", second(now(st_EU)));
  return 0;
}

Parameters

time	is the serial Julian date and time value.
