Converting seconds from float to int

Another small one on time precision that I’ve noticed.

package main

import (
	"fmt"
	"math"
	"time"
)

func main() {
	now := time.Now().Add(time.Hour)
	seconds = time.Now().Sub(now).Seconds()
	fmt.Println(int(seconds))
	fmt.Println(int(math.Floor(seconds)))
}

Line 12 will print -3599, line 13 will print -3600 (tested on Ubuntu). So watch out when converting the number of seconds to an integer, you might not always get what you need.
