DTS can convert among several types of binary time structures that are based on different base dates and time unit measurements. DTS uses UTC-based time structures and can convert other types of time structures to its own presentation of UTC-based time. The DTS API routines are used to perform these conversions for applications on your system.
The following table lists the absolute time structures that the DTS API uses to modify binary times for applications.
Absolute Time Structures
| Structure | Time Units | Base Date | Approximate Range |
| utc | 100-nanosecond | 15 October 1582 | A.D. 1 to A.D. 30,000 |
| tm | second | 1 January 1900 | A.D. 1 to A.D. 30,000 |
| timespec | nanosecond | 1 January 1970 | A.D. 1970 to A.D. 2106 |
Relative Time Structures
| Structure | Time Units | Approximate Range |
| utc | 100-nanosecond | +/- 30,000 years |
| tm | second | +/- 30,000 years |
| reltimespec | nanosecond | +/- 68 years |
