Could not run job at specific time when daylight saving time switches

[reorx]

Code:

gocron_test.go

package main

import (
	"time"
	"fmt"
	"github.com/jasonlvhit/gocron"
)

func main() {
	fmt.Println("start main")
	go func() {
		for {
			time.Sleep(time.Duration(3*time.Second))
			now := time.Now()
			fmt.Println("	(now", now, time.Local, ")")
		}
	}()
	gocron.Every(1).Day().At("01:59").Do(pri1)
	gocron.Every(1).Day().At("03:01").Do(pri2)
	<- gocron.Start()
}

func pri1() {
	now := time.Now()
	fmt.Println("do 1 !!!", now)
}

func pri2() {
	now := time.Now()
	fmt.Println("do 2 !!!", now)
}

The time zone is set to America/New_York, and the date time is set to 2017-03-12 01:58:50 by sudo timedatectl set-time "2017-03-12 01:58:50" && sudo hwclock -w

Output:

[vagrant@localhost ~]$ ./settime.sh && go run ./test_gocron.go
Sun Mar 12 01:58:51 EST 2017
start main
	(now 2017-03-12 01:58:54.789104654 -0500 EST Local )
	(now 2017-03-12 01:58:57.78959527 -0500 EST Local )
	(now 2017-03-12 01:59:00.793605829 -0500 EST Local )
do 1 !!! 2017-03-12 01:59:00.793731129 -0500 EST
	(now 2017-03-12 01:59:03.797613207 -0500 EST Local )
	(now 2017-03-12 01:59:06.798436061 -0500 EST Local )
	...
	(now 2017-03-12 03:00:51.833313996 -0400 EDT Local )
	(now 2017-03-12 03:00:54.83476427 -0400 EDT Local )
	(now 2017-03-12 03:00:57.836203538 -0400 EDT Local )
	(now 2017-03-12 03:01:00.838035849 -0400 EDT Local )
	(now 2017-03-12 03:01:03.839273531 -0400 EDT Local )
	(now 2017-03-12 03:01:06.840455311 -0400 EDT Local )

The output shows that gocron.Every(1).Day().At("01:59").Do(pri1) runs properly, but gocron.Every(1).Day().At("03:01").Do(pri2) doesn't take any effect.

P.S. after 2017-03-12 01:59:59, daylight saving time switches from EST to EDT

I had similar issue too. Guess in func (j *Job) At(t string) *Job, the now timestamp has to use the loc timezone. Something like time.Now().In(loc)
