Determination of local time at vehicle ignition

1. A system for updating vehicle time information, comprising:

a communication device configured to wirelessly communicate with a wireless network using a network communication protocol; and

a processing unit configured to perform:

assessing communications between the communication device in a vehicle and the wireless network to determine whether a condition related to a potential local time offset error exists;

based on determining that the condition exists, transmitting a message supported by the communication protocol to the wireless network, the message requesting a change in a communication parameter associated with the communication device as defined by the communication protocol, the change in the communication parameter configured to prompt the wireless network to return a response message including a local time offset; and

updating a vehicle local time record based on the local time offset.

2. The system of claim 1 , wherein the wireless communication network is a wireless broadband network.

3. The system of claim 1 , wherein the processing unit is configured to assess the communications based on a change of a vehicle state.

4. The system of claim 3 , wherein the change in the vehicle state includes a change from an ignition OFF state to an ignition ON state.

5. The system of claim 3 , wherein the change in the vehicle state includes a transition between a first time zone and a second time zone.

6. The system of claim 1 , wherein the condition includes a daylight savings time (DST) local time change occurring subsequent to a previous time update received by the communication device from the wireless network.

7. The system of claim 1 , wherein the wireless network is a Long Term Evolution (LTE) network, and the communication parameter is a discontinuous reception cycle (DRX) period.

8. The system of claim 1 , wherein the communication device is a telematics unit disposed in the vehicle.

9. A method of updating vehicle time information, comprising:

assessing communications between a communication device in a vehicle and a wireless network using a network communication protocol, wherein the assessing includes determining whether a condition related to a potential local time offset error exists;

based on determining that the condition exists, transmitting a message supported by the communication protocol to the wireless network, the message requesting a change in a communication parameter associated with the communication device as defined by the communication protocol, the change in the communication parameter configured to prompt the wireless network to return a response message including a local time offset; and

updating a vehicle local time record based on the local time offset.

10. The method of claim 9 , wherein the wireless communication network is a wireless broadband network.

11. The method of claim 9 , wherein the assessing is performed based on a change of a vehicle state.

12. The method of claim 9 , wherein the condition includes a daylight savings time (DST) local time change occurring subsequent to a previous time update received by the communication device from the wireless network.

13. The method of claim 9 , wherein the wireless network is a Long Term Evolution (LTE) network, and the communication parameter is a discontinuous reception cycle (DRX) period.

14. The method of claim 9 , wherein the communication device is a telematics unit disposed in the vehicle.

15. A vehicle system comprising:

a memory having computer readable instructions; and

a processing device for executing the computer readable instructions, the computer readable instructions controlling the processing device to cause the processing device to perform:

assessing communications between a communication device in a vehicle and a wireless network using a network communication protocol, wherein the assessing includes determining whether a condition related to a potential local time offset error exists;

based on determining that the condition exists, transmitting a message supported by the communication protocol to the wireless network, the message requesting a change in a communication parameter associated with the communication device as defined by the communication protocol, the change in the communication parameter configured to prompt the wireless network to return a response message including a local time offset; and

updating a vehicle local time record based on the local time offset.

16. The vehicle system of claim 15 , wherein the assessing is performed based on a change of a vehicle state, the change in the vehicle state including a change from an ignition OFF state to an ignition ON state.

17. The vehicle system of claim 15 , wherein the condition includes a daylight savings time (DST) local time change occurring subsequent to a previous time update received by the communication device from the wireless network.

18. The vehicle system of claim 15 , wherein the wireless network is a Long Term Evolution (LTE) network, and the communication parameter is defined by a LTE protocol.
