Duplicate daylight savings time entries

I've followed the information in the guide (http://www.linux-watch.com/news/NS6300294422.html), and in several computers it worked great. Unfortunately, I've run into a bit of a roadblock. If I check it the 'standard way', it shows no change:

output of zdump -v /etc/localtime | grep 2007

Code:

/etc/localtime Sun Apr 1 09:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 PST isdst=0 gmtoff=-28800 
/etc/localtime Sun Apr 1 10:00:00 2007 UTC = Sun Apr 1 03:00:00 2007 PDT isdst=1 gmtoff=-25200 
/etc/localtime Sun Oct 28 08:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 PDT isdst=1 gmtoff=-25200 
/etc/localtime Sun Oct 28 09:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 PST isdst=0 gmtoff=-28800

but when I specify time zone...

output of zdump -v /etc/localtime PST8PDT | grep 2007

Code:

/etc/localtime Sun Apr 1 09:59:59 2007 UTC = Sun Apr 1 01:59:59 2007 PST isdst=0 gmtoff=-28800 
/etc/localtime Sun Apr 1 10:00:00 2007 UTC = Sun Apr 1 03:00:00 2007 PDT isdst=1 gmtoff=-25200 
/etc/localtime Sun Oct 28 08:59:59 2007 UTC = Sun Oct 28 01:59:59 2007 PDT isdst=1 gmtoff=-25200 
/etc/localtime Sun Oct 28 09:00:00 2007 UTC = Sun Oct 28 01:00:00 2007 PST isdst=0 gmtoff=-28800 
PST8PDT Sun Mar 11 09:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 PST isdst=0 gmtoff=-28800 
PST8PDT Sun Mar 11 10:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 PDT isdst=1 gmtoff=-25200 
PST8PDT Sun Nov 4 08:59:59 2007 UTC = Sun Nov 4 01:59:59 2007 PDT isdst=1 gmtoff=-25200 
PST8PDT Sun Nov 4 09:00:00 2007 UTC = Sun Nov 4 01:00:00 2007 PST isdst=0 gmtoff=-28800

So what does this mean? Does it mean I'm set, or that the system will be rather confused? I followed all the steps twice over, with no apparent changes. There wasn't a /usr/lib/zoneinfo folder, but for a cautionary measure, I created it and copied the files there as well (it mentioned having to copy the files to that location on 'older systems').

Is anyone else running into this? Is this going to be okay come March 11th?

It looks like the instructions you followed left out the last step (or, you overlooked it). You need to symlink the pst8dst file to /etc/localtime. That will finish it.

If, for some reason, the symlink doesn't work when you run zdump -v, then copy pst8dst to /etc/localtime.

Now that I think about it, run 'ls -l /etc/localtime'. If it's a symlink in your distro, it will point to the pst8dst file. Since it isn't working now, I suspect /etc/localtime is a copy of pst8dst.

Thanks! That was a quick fix, and now it makes sense. When using 'zdump -v /etc/localtime PST8PDT' I didn't realize it, but it was reading /etc/localtime *and* the file PST8PDT... it wasn't just a command option. Had I looked a little closer, that would have made sense!
