Getting User TimeZone

[amitkhosla]

Hello Sir,

How can we identity the calling user timezone?

Hi,

You would be able to do this by writing an IVR code that creates a database that does a lookup of the time zone of the user based on the user's area code.

Hello
Here is the php code to find the local time where the caller is calling from. In N. America. Any areacodes that are not listed are set to Central time. It's approximate and rough0-and-ready. But it works for most of the continent. Please publish errors and updates here so we can all share..

Code: Select all

function AreaCodeLocalTime ($AreaCode){
// this function returns a timestamp suitable for updating a mysql database timestamp field
// with the current time for the originating area code/ Built for IVR programs.
// http://en.wikipedia.org/wiki/Zoneinfo basic information
// http://en.wikipedia.org/wiki/Daylight_saving more than you wanted to know
// http://www.greatdata.com/pdf/ac-timezone.pdf one N. America table

//
// http://www.bennetyee.org/ucsd-pages/area.html this is the one I used...
// area code to offset to timezone in a separate program to generate this statement
