Appendix C: Time Zone Determination

This appendix describes how to determine the TimeZone parameter setting.

Time zones are based on the distance from Greenwich Mean Time (GMT), which is zero. Time

zones east of Greenwich, UK, go from +1 to +12. Time zones west of Greenwich, UK go from

-1 to -12.

The 4602 SIP Telephone uses the TimeZone parameter to set the Date and Time display. The

TimeZone parameter can be up to two ASCII characters. Because the phone does not accept a

plus (+) or negative (-) sign, you have to use a formula to obtain a numerical time zone value to

use.

Time Zone Calculation:

1. Use the

2. If the time zone is -1 to -12 (i.e., West of Greenwich, UK), eliminate the minus sign and use

the number as the TimeZone parameter value. For example, a phone site located in the

Eastern United States has an actual time zone of -5. Therefore the TimeZone parameter

value for that site is 5.

3. If the time zone is +1 to +12 (i.e., East of Greenwich, UK), subtract that number from 25 and

use the result as the TimeZone parameter value. For example, a phone site located in

Japan has an actual time zone of +9. Therefore, the TimeZone parameter value for that site

is 25 minus 9, or 16.
