3.6.4 Configuring Date and Time
Note: By default, date and time settings are automatically provisioned via the enterprise
DHCP server when the phone is connected to the Internet and to the power supply, but
you can manually change them if required. This section describes how.
The phone automatically retrieves date and time from a Network Time Protocol (NTP) server
when it is connected to the Internet. NTP is a protocol for distributing Coordinated Universal
Time (UTC) by synchronizing the clocks of computer systems over packet-switched,
variable-latency data networks.
You can configure Daylight Saving Time using the Configuration File.
 To configure Daylight Saving Time:
• Open the Configuration File page (Management tab > Manual Update >
Configuration File) and configure the parameter using the table below as
reference.
Table 3-52: Daylight Saving Time Parameters
