Apache 2007 Daylight Savings Time Question

Apache 2007 Daylight Savings Time Question

Product:  Apache Tomcat 4.1
Server:  Windows Server 2003:

As you may be aware, daylight savings time (DST) has been moved from the first Sunday in April to the second Sunday in March (3/11).  I am a manager at a large corporation and I am working with some of our developers to address potential issues with 2007 DST.  Our application is a vendor-purchased application that we purchased about a year ago.  They are using Apache Tomcat 4.1 which is a non-standard product for the company that I work for and there is little knowledge about what is required to ensure that we will not be affected by the 2007 DST change.

My questions are:

1.  Can someone please provide information on what is required to ensure that we are not affected by the 2007 DST change?
2.  It appears that Apache Tomcat 4.1 does not come bundled with its own JRE.  Would we simply need to upgrade the jre that is installed on the server?

For question number 2 one of my developers has mentioned that through some of his research, he has found that Apache uses the JRE that is installed on the server and this JRE communicates with the OS to get date/time information.  We think that upgrading the JRE that is installed on the server and then regression testing the application to ensure we didn't break anything might do the trick.  Since we don't really have any Apache knowledge experts here, your expert assistance would be greatly appreciated.

Thank you,

kpetti

I cant vouch for TomCat but as an Apache Module it should inherit its time and date information from the OS (windows serer 2003 in your case)

Apache will use whatever date and time the Operating system has so if it changes for DST then the time apache has will also change (apache doesent use timezones persay) if you use PHP (another module) then its quite happily to read the timezone information with windows and if you write a date/time based script and change the time the reflected time is instant.

rhickmott,

The company that I work for distributed a patch to our servers.  This replaced some of the files in the JDK that Apache uses and addressed the DST issue

Ah ok no problem :)

Good to see you have it sorted.

rhickmott,

I did want to say thank you for attempting to answer my question and I don't mean to offend you in any way, but your answer ultimately was not the solution for my issue.  Given that the question was worth so many points and we went with an alternative solution, is there a way that I can grade the answer, but not award such a high amount of points.  Again, I very kindly appreciate your assistance so please do not take my question the wrong way.

Thank you,
kpetti

The usual way is to post a request in the cleanup area asking for them to refund the points and close the question.

Either than or grade it a C and it will give out 500 point.

Well their was a solution there it just wasent mine ;) It would seem the problem was a software bug and fixed with a patch so in a way the OP answered his own question.

I was simply responding to the "is there a way that I can grade the answer, but not award such a high amount of points"

Eiher way it makes no odds to me :)
