Abstract

An apparatus, and an associated method, estimates a time zone at which an electronic device, such as a wireless device, is positioned. Parameters, such as a mobile country code, a GMT offset, a daylight savings time parameter, and geo location parameters are all candidate parameters from which to make an estimate. Received parameters are identified, and selectably used to obtain an estimate that is matched or verified to ensure likely accuracy.
