TimeZone Issue during DayLight Saving I just been bugged by the Day light saving hours 

I seem that 3rd November 2013 01:00:00 start EST time 

Now ever Time I set my time to 3rd November 2013 00:58:xx(some seconds) 

and run date 

it give me valid Time zone i.e EDT 

but 

even after the time pass 01:00:00 and I still query the date library 

I still see the Time zone as EDT and not EST

have a look at this screenshot 

You can clearly see the Time zone saying as EDT even when it is EST 

any one has a clue for this 

Update

There is one other finding I found if I restart my machine I see this



More Update

Before Restart 
   

After Restart
What was the current time and timezone when you set the clock ?

In any case, use date -u to figure out what exactly the system clock is set to.

EST time doesn't start at 01:00 but at 02:00 which turns to 01:00 EST.
