Does InterMapper handle changes to Daylight Savings Time (DST)?
(Updated 16 Feb 2007) Yes. Or more precisely, current versions of InterMapper will work properly as long as the underlying operating system and Java virtual machine have been updated to handle the change of Daylight Savings Time. InterMapper and RemoteAccess always use UTC internally, but use the underlying environment's time facilities to convert to the local time that's displayed in log files and chart data.
As long as your OS/JVM have been updated, InterMapper will continue to operate properly. We have received information that the following environments have been patched and/or updated.
Background Information
In the US, Daylight Savings Time will begin earlier and end later, starting in 2007 as mandated by the U.S. Energy Policy Act of 2005. Other countries are implementing similar changes. The patches above will ensure that your computer works properly with the US2007DST time changes.
Jennifer Mears wrote an interesting article on Network World that describes the interaction between network time servers and operating systems regarding the DST switch.
