1. A method for automatically providing a local time zone setting for a device comprising:
- obtaining a location estimate of a present location of the device within a geographical area and a present date and time;
identifying a cell of a grid depicting a graphical area comprising the location estimate, wherein the cell is subject to first time zone application rules, wherein in response to determining that the cell is subject to two or more time zones, identifying a first sub-cell, within the cell, comprising the location estimate, the first sub-cell being subject to second time zone application rules; and
automatically providing the local time zone setting and the present date and time at least partially based on;
the first time zone application rules at least partially in response to the determining that the cell is subject to a single time zone, orthe second time zone application rules at least partially in response to the determining that the cell is subject to the two or more time zones.

Abstract
A local time zone setting for a device is automatically provided based on a location and a date and time. Location information is obtained for a present location of the device within a geographical area and the date and time. An association is established between the present location and a geopolitical portion of the geographical area, the geopolitical portion including time zone application rules. The local time zone setting is automatically provided based on the time zone application rules, which can include daylight savings time (DST) participation, and the present date and time.
