[LUNI] DST changes :: a how to for Linux boxes

[Mike Scott]

Well, I followed all the steps and it seemed to work.
I verified that the files in /usr/share/zoneinfo all have today's date
(were replaced).
But when I type the final verification command, I get the old data:

[root at prideth root]# zdump -v /etc/localtime | grep 2007
/etc/localtime  Sun Apr  1 07:59:59 2007 UTC = Sun Apr  1 01:59:59 2007
CST isdst=0 gmtoff=-21600
/etc/localtime  Sun Apr  1 08:00:00 2007 UTC = Sun Apr  1 03:00:00 2007
CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 06:59:59 2007 UTC = Sun Oct 28 01:59:59 2007
CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 07:00:00 2007 UTC = Sun Oct 28 01:00:00 2007
CST isdst=0 gmtoff=-21600

However, if I add my timezone, it appears to give more info:
[root at prideth root]# zdump -v /etc/localtime CST6CDT | grep 2007
/etc/localtime  Sun Apr  1 07:59:59 2007 UTC = Sun Apr  1 01:59:59 2007
CST isdst=0 gmtoff=-21600
/etc/localtime  Sun Apr  1 08:00:00 2007 UTC = Sun Apr  1 03:00:00 2007
CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 06:59:59 2007 UTC = Sun Oct 28 01:59:59 2007
CDT isdst=1 gmtoff=-18000
/etc/localtime  Sun Oct 28 07:00:00 2007 UTC = Sun Oct 28 01:00:00 2007
CST isdst=0 gmtoff=-21600
CST6CDT         Sun Mar 11 07:59:59 2007 UTC = Sun Mar 11 01:59:59 2007
CST isdst=0 gmtoff=-21600
CST6CDT         Sun Mar 11 08:00:00 2007 UTC = Sun Mar 11 03:00:00 2007
CDT isdst=1 gmtoff=-18000
CST6CDT         Sun Nov  4 06:59:59 2007 UTC = Sun Nov  4 01:59:59 2007
CDT isdst=1 gmtoff=-18000
CST6CDT         Sun Nov  4 07:00:00 2007 UTC = Sun Nov  4 01:00:00 2007
CST isdst=0 gmtoff=-21600

So I think it will be okay, but I'll know for sure on Sunday.
(God Bless the USA!)
Has anyone else tried this?  I'm using RedHat 7.3.
