Abstract

Systems and methods for implementing a multi-word UTC time stamp using a single-word UTC time stamp and a multi-word key are disclosed. Embodiments may include creating a data file and creating a single-word time stamp to associate with the data file. Embodiments may further include creating a multi-word configuration key to associate with the single-word time stamp, wherein the configuration key comprises a time zone offset value, a seasonal time offset value, a standard time mnemonic, and a seasonal time mnemonic. Some embodiments may also include storing, In memory, the data file, single-word time stamp, and configuration key.

Claims

1. A method for implementing a multi-word coordinated universal time (UTC) time stamp using a single-word UTC time stamp and a multi-word key,

creating, by a processor, a data file;

creating, by the processor, a single-word time stamp to associate with the data file, wherein at least one bit of the single-word time stamp specifies a format of the single-word time stamp, at least one bit of the single-word time stamp indicates whether or not a seasonal offset is in effect, and a remainder of the bits of the single-word time stamp specify a time in a UTC time base;

creating, by the processor, a multi-word configuration key to associate with the single-word time stamp, wherein the configuration key comprises a time zone offset value, a seasonal time offset value, a standard time mnemonic, and a seasonal time mnemonic; and

storing, by the processor, in memory, the data file, single-word time stamp, and configuration key.

2. The method of claim 1, wherein the processor operates in an operating system environment in which the default time stamp format is different than the format of the single-word time stamp.

3. The method of claim 1, wherein the configuration key is associated with multiple single-word time stamps.

4. The method of claim 1, further comprising embedding the single-word time stamp and configuration key in the data file, and storing the data file.

5. The method of claim 1, further comprising storing the configuration key in memory when the processor is booted or rebooted.

6. The method of claim 1, further comprising:

retrieving the single-word time stamp and configuration key from the memory; and

creating a multi-word time stamp having a different format than the single-word time stamp based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.

7. The method of claim 6, further comprising displaying time specified in the retrieved single-word time stamp as one of limited time and fully qualified time based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.

8. A computer program product, comprising:

a non-transitory computer readable medium comprising instructions that, when executed by a processor of a computing system, cause the processor to perform the steps of;

creating a data file;

creating a single-word time stamp to associate with the data file, wherein at least one bit of the single-word time stamp specifies a format of the single-word time stamp, at least one bit of the single-word time stamp indicates whether or not a seasonal offset is in effect, and a remainder of the bits of the single-word time stamp specify a time in a UTC time base;

creating a multi-word configuration key to associate with the single-word time stamp, wherein the configuration key comprises a time zone offset value, a seasonal time offset value, a standard time mnemonic, and a seasonal time mnemonic; and

storing, in memory, the data file, single-word time stamp, and configuration key.

9. The computer program product of claim 8, wherein the processor operates in an operating system environment in which the default time stamp format is different than the format of the single-word time stamp.

10. The computer program product of claim 8, wherein the configuration key is associated with multiple single-word time stamps.

11. The computer program product of claim 8, wherein the medium further comprises instructions that, when executed by a processor of a computing system, cause the processor to perform the step of embedding the single-word time stamp and configuration key in the data file, and storing the data file.

12. The computer program product of claim 8, wherein the medium further comprises instructions that, when executed by a processor of a computing system, cause the processor to perform the step of storing the configuration key in memory when the processor is booted or rebooted.

13. The computer program product of claim 8, wherein the medium further comprises instructions that, when executed by a processor of a computing system, cause the processor to perform the steps of:

retrieving the single-word time stamp and configuration key from the memory; and

creating a multi-word time stamp having a different format than the single-word time stamp based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.

14. The computer program product of claim 13, wherein the medium further comprises instructions that, when executed by a processor of a computing system, cause the processor to perform the step of displaying time specified in the retrieved single-word time stamp as one of limited time and fully qualified time based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.

15. An apparatus, comprising:

a memory;

a processor coupled to the memory, wherein the processor is further configured to perform the steps of;

creating a data file;

creating a single-word time stamp to associate with the data file, wherein at least one bit of the single-word time stamp specifies a format of the single-word time stamp, at least one bit of the single-word time stamp indicates whether or not a seasonal offset is in effect, and a remainder of the bits of the single-word time stamp specify a time in a UTC time base;

creating a multi-word configuration key to associate with the single-word time stamp, wherein the configuration key comprises a time zone offset value, a seasonal time offset value, a standard time mnemonic, and a seasonal time mnemonic; and

storing, in memory, the data file, single-word time stamp, and configuration key.

16. The apparatus of claim 15, wherein the processor operates in an operating system environment in which the default time stamp format is different than the format of the single-word time stamp.

17. The apparatus of claim 15, wherein the processor is further configured to perform the step of embedding the single-word time stamp and configuration key in the data file, and storing the data file.

18. The apparatus of claim 15, wherein the processor is further configured to perform the step of storing the configuration key in memory when the processor is booted or rebooted.

19. The apparatus of claim 15, wherein the processor is further configured to perform the steps of:

retrieving the single-word time stamp and configuration key from the memory; and

creating a multi-word time stamp having a different format than the single-word time stamp based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.

20. The apparatus of claim 19, wherein the processor is further configured to perform the step of displaying time specified in the retrieved single-word time stamp as one of limited time and fully qualified time based, at least in part, on processing of the retrieved single-word time stamp and the configuration key.
