>From a login on a machine with rhel4u2 I can execute the following commands and get the indicated output: date --date="Mar 25 15:00:00 UTC 2006" Sat Mar 25 10:00:00 EST 2006 date --date="Mar 25 15:00:00 UTC 2007" Sun Mar 25 11:00:00 EDT 2007 As you can see, the output differs for 2006 and 2007. That indicates that rhel4u2 includes changes required by the "Energy Policy Act of 2005," which mandates new dates for transition between Standard Time and Daylight Saving Time starting in 2007. If I do the same thing on a machine with "CentOS release 4.2 (Final)", I get the following output: date --date="Mar 25 15:00:00 UTC 2006" Sat Mar 25 10:00:00 EST 2006 date --date="Mar 25 15:00:00 UTC 2007" Sun Mar 25 10:00:00 EST 2007 So it looks as if CentOS4.2 does not yet have that change. Is that correct? Or is there perhaps some installation parameter that I have missed in installing CentOS4.2? Thanks for any info. Stowe Davison
