Operational IP Phone Features Time and Date
In addition to enabling/disabling the time server, you can also set the time and
date, set the time and date format, set the time zone, and set daylight savings time
on the IP phones. You configure these features using the configuration files, the IP
Phone UI, or the Aastra Web UI. The following table identifies which method of
configuration applies to each feature.
Daylight Savings Time (DST) Information
The Aastra IP Phones incorporate the federally mandated DST observance
change. This change became affective starting in 2007.
The US has made a change to its daylight savings time observance starting in
2007. The Energy Policy Act of 2005 mandates that DST will now begin at 2:00
A.M. on the second Sunday in March and revert to Standard time on the first
Sunday in November.
The changes to daylight savings time applies to the U.S. and Canada, but may
impact other countries outside North America.
