Cause

After changing daylight savings time settings, the card takes roughly 60 to 90 seconds to jump the system forward or backward 1 hour. Keep in mind the web interface is static. Reloading the page a few minutes later should reflect the new time.

Resolution

If you continue to have difficulty, try rebooting the card using the reset button on the card or using the "Reboot Management Interface" option in the web interface. This will not have an effect on the output of the device.

It is also recommended to update the network enabled device to the latest firmware found on the Software & Firmware section of the APC website.
