Linksys SPA9x2 Phone Administration Guide 79
Localizing Your SPA9x2 Phone
Setting Regional Parameters
• Manual Setup—The SPA9x2 phone also lets you manually enter the current time and
date from the phone GUI or the web UI. However, this value is overridden by the NTP
time or SIP Message Date whenever they are available to the phone. Manual setup
requires you to enter the time in 24-hour format only.
The time served by the NTP Server and the SIP Date Header are expressed in GMT time. The
local time is obtained by offsetting the GMT according to the time zone of the region.
The Time Zone parameter can be configured from the web page or through provisioning. This
time can be further offset by the Time Offset (HH/mm) parameter, which must be entered in 24-
hour format. This parameter can also be configured from the phone’s LCD display.
NOTE: The Time Zone and Time Offset (HH/mm) offset values are not applied to manual time and
date setup.
Configuring Daylight Savings Time
The SPA9x2 phone supports auto adjustment for daylight saving time (DST). You must set
Daylight Savings Time Enable to yes and enter the DST rule. This option affects the time stamp
on CallerID.
To enter the rule for calculating DST, include the start, end, and save values separated by semi-
colons (;) as follows:
Start = start-time; end=end-time; save = save-time, for example, the default DST rule is
start=4/1/7;end=10/-1/7;save=1.
•The start-time and end-time values specify the start and end dates and times of daylight
saving time. Each value is in this format: month/day/ weekday[/HH:mm:ss]
–The month value equals any value in the range 1-12 (January-December).
–The day value equals any + or - value in the range 1-31. If day is 1, it means the
weekday on or before the end of the month (in other words the last occurrence of
weekday in that month).
–The weekday value equals any value in the range 1-7 (Monday-Sunday). It can also
equal 0. If the weekday value is 0, this means that the date to start or end daylight
saving is exactly the date given. In that case, the day value must not be negative. If
the weekday value is not 0 and the day value is positive, then daylight saving starts
or ends on the weekday value on or after the date given. If the weekday value is not
0 and the day value is negative, then daylight saving starts or ends on the weekday
value on or before the date given.
– Optional time values: HH represents hours (0-23), mm represents minutes (0-59). and
ss represents seconds (0-59). Optional values inside brackets [ ] are assumed to be 0
if not specified. Midnight is represented by 0:0:0 of the given date.
•The save-time value is the number of hours, minutes, and/or seconds to add to the
current time during DST. The save-time value can be preceded by a plus (+) or minus (-)
sign to indicate addition or subtraction.
