Abstract

Embodiments of the present disclosure provide systems and methods for synchronizing computer time in a computer manufacturing environment. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. The system includes a computer network with a server maintaining timing information, the server communicatively coupled to a newly assembled computer via the computer network; time configuration logic which can be executed on the newly assembled computer which performs the actions of retrieving timing information from the server; and configuring a local clock on the newly assembled computer to a date and time corresponding to the timing information; and time transmittal logic which can be executed on the server which performs the action of transmitting the timing information over the computer network. Other systems and methods are also provided.

Claims

1. A system for synchronizing computer time in a computer manufacturing environment, comprising:

a computer network with a server maintaining timing information, the server communicatively coupled to a newly assembled computer via the computer network, wherein the computer network is localized within the manufacturing environment and not connected to external networks;

time configuration logic which can be executed on the newly assembled computer which performs a synchronization process, the synchronization process comprising;

retrieving timing information from the server;

configuring a local clock on the newly assembled computer to a date and time corresponding to the timing information; and

storing time zone information obtained from the timing information on a restricted area of a hard drive of the newly assembled computer; and

time transmittal logic which can be executed on the server which performs the action of transmitting the timing information over the computer network.

2. The system of claim 1, further comprising:

an installation process which can be executed on the newly assembled computer which performs the actions of automatically configuring time settings maintained by an operating system of the newly assembled computer according to timing information maintained on the local clock of the newly assembled computer and stored in the restricted area.

3. The system of claim 1, further comprising a newly manufactured computer system connected to the network and a synchronization process executing on the newly manufactured computer system.

4. The system of claim 1, further comprising:

a download process which can be executed on the newly assembled computer which performs the actions of retrieving software from a data server on the computer network and installing software from the data server on a hard drive of the assembled computer.

5. The system of claim 4, wherein the synchronization process is initiated as part of a diagnostic testing process after the download process.

6. The system of claim 4, wherein the synchronization process is initiated as part of the download process.

7. The system of claim 4, wherein the computer network is a restricted network within a manufacturing facility.

8. The system of claim 1, wherein the server periodically transmits timing information at least every thirty seconds.

9. The system of claim 1, wherein the synchronization process performs the action of adjusting incoming timing information by clock skew detected on the incoming timing information.

10. A system for synchronizing computer time in a computer manufacturing environment, comprising:

means for transmitting timing information over a computer network to be used in synchronizing an internal clock of a manufactured computer system with the timing information wherein the computer network is localized within the computer manufacturing environment and not connected to external networks;

means for receiving the timing information from the computer network;

means for setting an internal clock of the manufactured computer system to correspond to received timing information; and

means for storing time zone information obtained from the timing information on a restricted area of a hard drive of the manufactured computer system.

11. The system of claim 10, further comprising:

means for tracking the manufactured computer system within the manufacturing process, wherein the means for tracking enables the manufactured computer system to retrieve the timing information.
