Question

Daylight Savings in CF 9 for Linux

How do I fix the time in coldfusion to match that on my server?

The coldfusion time is always 1 hour behind the present server time.

I am running Red Hat Enterprise Linux 6.

    While parts of this thread were helpful, I obtained my final solution from:

    what does this tell you?

    dst

    savings:=#dstSavings#");

    </cfscript

    That these "jive" forums chew up responses and spit them out like garbage.

    it wouldn't be so bad but i already knew it might do that.

    pretend this is wrapped in a cfscript block....

    jre=createObject("java","java.lang.System");

    JREname=jre.getProperty("java.runtime.name");

    JREversion=jre.getProperty("java.runtime.version");

    tz=createObject("java","java.util.TimeZone").getDefault();

    tzName=tz.getDisplayName(true,tz.LONG);

    dstSavings=tz.getDSTSavings()/3600000;

    writeoutput("jre:=#JREname# #JREversion#
    tz:=#tzName#


    dst savings:=#dstSavings#");

    interesting side effect is that i found out oracle thinks there's an "Indochina

    Summer Time" with a DST savings of "0". oh those kidders

    ColdFusion does not maintian its own time data.

    ColdFusion gets the time from Java

    AFAIK, Java gets the tme from the server.

    What version of Java do you have installed?  If you somehow have an older version of Java, it may not be updated to the new US daylight savings rules that went into affect in 2007.  Presuming you and your server are in the US.

    Is everything configured to the correct timezone for where you are located?

    That is a pretty recent version of Java (I suspect it is the one that comes with CF9).

    IIRC, you *could* update to 1.6.0_20 as the latest version tested and supported with CF9.  According to this article [http://www.petefreitag.com/item/786.cfm] 1.6.0_24 will soon be offically tested and supported.

    You would have needed to have had a very old version of Java (something before 1.4.2_11) which I'm not sure would even work with CF9.  But you do still find people using systems that have not been updated since those versions were released.

    Have you confirmed what timezone the server thinks it lives in?
