Develop on Series 40 Platform.
Need a development hack to the standard Contacts database.
Want to display a new feild "Local Time" in the Contacts interface. This is a read only feild (no entry). "Local Time" is derived from system time of the Phone + offset.
Offset worked out from the default telephone number for that contact -> lookup table (containing prefixes + offset value) supplied.
Result -> Providing the local time in the contact details for each contact stored. Derived from the default number for that contact and a lookup table that identifies appropiate 'offset' from system time.
