United States Daylight Savings Time Changes in 2007

US regions that do not observe Daylight Savings Time, including most of Arizona, Hawaii, and several territories, do not need to adjust anything due to these changes. The technical note only applies to US regions where Daylight Savings Time is observed.

Starting in 2007, the United States is changing the dates during which Daylight Savings Time is observed. Daylight Savings Time will start at 2 AM on the second Sunday of March and end at 2 AM on the first Sunday of November.

EZproxy obtains its Daylight Savings Time information directly from the operating system, so no update to EZproxy is required due to this change. However, operating systems do need to be updated to reflect these changes. The following links provide information on how to update your operating system for this change.

Linux

To verify whether or not your Linux system has been updated to reflect these changes, issue the command:

zdump -v /etc/localtime | grep 2007


If the results show March 11 and November 4, your system has been updated and no further action is required.

If the results show April 1 and October 28, your system has not been updated and you will need to find timezone update information for your distribution of Linux.
