Works fine in the US Central time zone:

    [rj at mavis ~]$ date --date="Mar 25 15:00:00 UTC 2006"
    Sat Mar 25 09:00:00 CST 2006
    [rj at mavis ~]$ date --date="Mar 25 15:00:00 UTC 2007"
    Sun Mar 25 10:00:00 CDT 2007

Do you have tzdata-2005m-1.EL4 installed?

    [rj at mavis ~]$ rpm -qi tzdata

    relocatable)
