Question

CF MX and Daylight Savings Time Change

  • September 19, 2006

Next year 2007, the Daylight Saving day (chaning the clocks for spring and fall) will be changing. The Spring date will be a month earlier and the fall date a month later then it has been for years.

How will the Cold Fusion Server for MX 7+ handle this? Will it use the server time or use the internal CF Server clock?

Thanks.

    It seems our IT folks pushed a new Microsoft Daylight patch to our CF server (win2k) and now the function "#now()# shows gmt and not system time

    It isn't so much that ColdFusion has the problem as its underlying technology, Java, will.

    Other Java based app servers are needing patches too.

    Adboe has released a technote for this issue.

    The technote for this issue:
    http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=d2ab4470 has another link to a technote which addresses null pointer exceptions after upgrading the JVM on CFMX 6.1 systems: http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=kb400232 The hotfix described in that technote gives a fix for CFLDAP and CFSERVLET tags after the new JVM is installed.

    The important thing to note is that Adobe feels that daylight savings time will indeed present a problem for ColdFusion applications. Unfortunately, the problems are not explained in any detail. I can guess that functions like DateDiff( ) may calculate incorrect values when spanning the changed weeks of daylight savings time. As others have suggested; however, simply retrieving the system time, i.e. Now( ) function may not be affected as long as the operating system clock is set correctly.

    Hope that helps.

    It's only moving by a month total. 2 weeks earlier in March and 2 weeks later into November. Orginially it was 2 months, but it was backed down.

    Cf uses Server time, so just adjust the time on the server to how you want it to be.
