EDT: Clock won't change?

Is there something special I need to do to keep my system at the correct time here? I just emerged ntp last night, and even that didn't change the clock to account for EDT...

My system is off by exactly one hour. I looked through the timezones directory to see if there's an EDT, and there isn't... I'm pretty sure I've read the solution before, I just can't seem to find it.

Any help on changing my clock would be greatly appreciated!

Thanks.

Hmmm... perhaps a result of daylight savings time?
Try: "ntpdate time.nist.gov". If you are looking at your clock via KDE, also right click on the clock and reselect Show Timezone > America/New York.

I've been having issues with my clock since installing Gentoo last week, and I've tried a couple of different symlinks (going from the zoneinfo list). My final try will be PST8PDT, although I would think that setting it to /US/Pacific would have accounted for the daylight savings shift. To the best of my knowledge, the entire US Pacific coast uses daylight savings (not counting Alaska, I'd have tah ask 'er). Hrm.

have /etc/localtime pointing to /usr/share/zoneinfo/EST5EDT

(I think EST is just for those that don't go onto daylight savings)

What is the result if you run the date command? My guess is that it still has you in the normal winter timezone, rather than the equivalent Daylight time. For the Eastern timezone. make sure you are set to EST5EDT - this basically means that the standard zone is EST, that its a 5 hour difference, and you use EDT during Daylight Savings Time. Time syncing wont work as it is technically giving you the right time, its just that your computer isn't handling the timezone right.

I have had my /etc/localtime linked to EST5EDT for years, and it has worked in the past for changing the clock automatically for daylight savings time. But for some reason this time it didn't work. Now my time is an hour off and NTP isn't changing it. As far as I know, my clock is set correctly but for some reason the time zone display is malfunctioning for daylight savings time.

Anyone else have trouble even with your computer set to EST5EDT?

EDIT: I just checked the date command, and my computer does in fact know that it has switched over to EDT, because it now says EDT instead of EST. The time just didn't change, weird. I wonder if my local NTP server is keeping incorrect time...

I just setup ntp and I had the same thing.
My time was an hour late.

I did have /etc/localtime pointing to EST so I changed it to point to EST5EDT and now the date command indeed returns the right time.

I dont know and anyone please correct me if i am wrong but ntp probably retrives the gmt time (as in unix timestamp , its same everywhere in the world) anyway and its up to local system to make the adjustments.
